In order to do what, exactly?
win a super bowl of course.
We have positions all over to be improved upon, but you're never, ever going to have all pros at every position. I think every Dlineman could be improved upon. Daniels is the only guy I really like. The rest are just guys, but those "guys" were good enough to get it done last year, save for a monumental team collapse, the likes not often seen in the NFL but it happened.
I think between Hayward, Shields, Dix, Burnett, Hyde we have a secondary good enough to win it all. I think we need depth, but I think right now we have guys that can get it done.
We have an OLB playing ILB and another guy that is ok and that was good enough last year, again except for the 5 minute collapse. I think the other guys we have at OLB do an above average job with Peppers doing much better than average job.
I think we'll have a top offense in yards and scoring again next year even if we don't add anybody.
so do we "need" to improve? besides focus and execution, no, I don't think we "need" to. I think the guys right now could get it done, assuming good health all year which rarely happens, so that should be improved upon and I trust those guys to get the guys in the draft.
what would I like to see improved? I still think we can have better LT play. I think our young center will continue to grow. QB? I think we're good. WR? Just fine. TE? we can upgrade, but I think our young guy will prove himself this year. we don't need Gronk, we just need someone that can turn around and catch a ball for a 1st down 30 times a year. I think our offense has more than enough weapons. RB? I think we're fine. It would be nice to have another guy for that 3rd down guy but Lacey and Starks are more than capable.
on Defense, NT could be upgraded, but then we have the same guys as last year and a big wait and see on Raji. Some of those young guys should continue to improve along that line. ILB could be improved, both positions, but Matthews and Barrington can get it done if need be. I think OLB is fine with Peppers and the other guys are good enough, though they could definitely be upgraded. and secondary, I already said I think the guys we have are good enough, though besides Shields there are better players than all of them playing in this league and Shields definitely needs to work on his focus and consistency still. But expecting all the guys better to play on this team is a bit unrealistic.
