^I don't think Njoku is because you have a similar skill-set with Herndon. You lose some of his play-making ability, but you can still do some of the things with Herndon that you do w/ Njoku.
^Instead of Elder, who you know what he'll give you, I'd put in Redwine. If he's weak - they'll be throwing at him all year.
^Instead of Willis, I'd put the DT position in general. The run defense last year was bruuuuuuuuuuuutal. Absolutely brutal.
^Whoever ends up playing RT.
That list is a mix of best players, and most important players. There's a big distinction, in my opinion, between the two.
