This is too vague. If it's all about last year, then Bowens wouldn't be listed. If it's about the best players, then Bowens deserves it because the guy is a run-stopping tank. Last season with our defensive line we had the best rush defense in the conference and the second best in the league at 3.3 YPC. This certainly warrants more attention for the defensive line, all of which are still around except for Ogunleye.
Cornerbacks are debatable. I had an argument with a Bills homer a while back about Clements and Surtain, with him making the claim that any GM in the league would rather have Clements. Now, it's plain as day that Surtain is the best cornerback in the division. Based on last year alone, Surtain did a very good job of shutting down a lot of the top receivers that we faced. I went through it in the past but I can't the post anymore. I remember who Surtain typically covered. It's tough to say that he was better than Clements last year (or vice versa) since both teams had dominating pass defenses.
Junior Seau is without a doubt the best career OLB in the division, but now he's behind Spikes. Willie and Barton don't belong with those two.
And on and on. It's not nearly as fun as a time-killer as I thought it would be.
