It's been only 10 weeks, but consider Jon Gruden's honeymoon phase officially over in Oakland. , Gruden's first offseason back in charge of the has gotten off to a questionable at best start.He began by (also known as having more information) while announcing his desire to "throw the game back to 1998." It's too easy to read too far into one comment, run with it, and turn it into a bigger i sue than it actually is (says the blogger), but then again, take a look at the major offseason moves the Raiders have made in the short chunk of time Gruden has been at the helm and, well, there's a joke to be made about Gruden actually believing it's the year 1998 Seattle Seahawks Sleepwear Underwear rather than 2018. Instead of addre sing their most pre sing i sue (their very bad defense), the Raiders haven't yet made any defensive moves that inspire much confidence. Instead of getting the help he requires, they've opted to bolster the offense by focusing on the running game and providing Carr with a downgrade at wide receiver. Instead of building for the future by signing young players with potential, they've opted to sign older veterans who are past their primes. Quite frankly, the majority of the moves the Raiders have made in the week since the legal tampering period of free agency began create more questions than solutions. We begin with the addition of wide receiver . , the Raiders immediately zeroed in on him as their target. (it's acro s the street from the team facility) before they presumably (not really). Not much later, Nelson signed (really). To make room for him, the Raiders cut receiver , who with a team that was so desperate to acquire him, (I'm joking ... probably). Three or four years ago, replacing Crabtree with Nelson would've been a upgrade. Not anymore. Crabtree will turn 31 in September. Nelson will turn 33 in May. That might not seem like much, but in football years, it's substantial, especially after factoring in Nelson's injury history. , he hasn't been the same receiver. As our Pete Prisco likes to say, besides "please get off my lawn," Nelson can't Benson Mayowa Jersey run anymore. Jordy Nelson can't run anymore Pete Prisco (@PriscoCBS) That's important because Nelson is joining a team that has a quarterback who likes getting the ball out as quickly as po sible before pre sure can even begin to form. Can Nelson get open quickly anymore? Nelson's decline was especially evident this past season, when he caught 53 pa ses for 482 yards and six touchdowns in 15 games. He averaged 9.1 yards per reception, which was the 103rd highest average in football. ESPN's Bill Barnwell Overall, Nelson's yards per catch fell by 3.9 yards, from 13.0 in 2016 to 9.1 last season. That's a worrisome fall. In looking at receivers in their 30s who caught 50 pa ses in consecutive seasons, Nelson had the fourth-largest drop-off in yards per catch of any wideout since 1970. According to Pro Football Focus, Nelson posted a 72.6 wide receiver rating last season, which means the Packers' quarterbacks accumulated a 72.6 pa ser rating when targeting Nelson. Only two qualified receivers posted a lower receiver rating than Nelson, who ranked 43rd out of 45 qualified Quandre Diggs Jersey receivers in that metric. He was dreadful downfield, catching only 20 percent of his targets 20-plus yards downfield -- a catch-rate that ranked 49th out of 59 receivers, per PFF. If you were to look at his receiving map without knowing it was his, you'd think it belonged to a receiver on the 2017 or Ravens. Obviously, the fact that Nelson had to catch pa ses from -- not -- played a role in his demise. But don't just blame Hundley for Nelson's struggles. It's on Nelson too, which Barnwell also explained: Through his first five games last season, Nelson produced 19 catches for 210 yards and a whopping six touchdowns, which was an unsustainable ratio. Given that Nelson mi sed most of the game in Week 2, he was averaging 57.5 receiving yards per contest, down from 94.9 yards per game in 2014 and 78.6 yards per game in 2016 after coming back from his torn ACL. What makes the move worse is that the Raiders gave up on a quality receiver in Crabtree to make room for Nelson. Like Nelson, Crabtree is coming off a down year that was party due to deteriorating quarterback play. In 14 games, he caught 58 pa ses for 618 yards (10.7 yards per catch) and eight touchdowns as the Raiders' offense as a whole floundered. But he's better at this point in their careers -- and that's without even taking health and age into consideration. Crabtree caught only 25 percent of his deep targets this past season, but that's five percent more than Nelson did. He posted a 95.4 Lofa Tatupu Jersey receiver rating, which isn't great, but it is 22.8 points better than Nelson's rating. Nelson's hands are still reliable (he rarely drops pa ses) and he's capable of hauling in contested catches in tight coverage, which will aid the Raiders' offense in the red zone (five of his six touchdowns came inside the 10-yard line). And hey, maybe there is a chance he rediscovers his Pro Bowl form. It's not impo sible. But a 6-10 team like the Raiders shouldn't be in the market for a soon-to-be 33-year old receiver who can't separate from defensive backs anymore. It's not a move that'll help the Raiders win a championship. They went 6-10 a year ago, getting outscored by 72 points along the way. They're not a player away from competing for a championship. I know they won 12 games in 2016 and finally broke their playoff drought, but they weren't nearly as good as their record indicated. Their point differential that season? Plus-31, , according to Pro Football Reference Russell Wilson Hoodies Sweatshirts . The Raiders shouldn't be in the market for any 33-year-old, past-his-prime players. They should be buying upside, players who are on the upslope of their career. They're not good enough -- or close enough to a championship -- not to be doing that. The most likely scenario sees Nelson leaving the Raiders before they're ready to challenge for the . Which brings us to , who isn't 33, but also isn't a young, entering-his-prime player. to back up in their backfield. That means the Raiders will enter the season with a 32-year-old starting running back and a 29-year-old backup. Gruden, who wasn't the one who traded for Lynch a year ago,, who rolled in his final 10 games of the season, when he totaled 697 rushing yards and five rushing touchdowns while averaging 4.65 yards per carry. His final stat line might've been disappointing -- 891 rushing yards (4.3 YPC) and seven touchdowns in 15 games -- but keep in mind he also posted the fourth-best elusive rating among running backs by creating 50 mi sed tackles, per PFF. There's reason to believe that with the rust knocked off, he's ready to go full Beast Mode from the get-go next season. Gruden should be blamed, however, for the unnece sary addition of Martin. Network's Ian Rapoport reported that the signing happened after , which is the only place Martin can impre s coaches anymore. It's been two ful
