Jordan Nix (78) could provide much-needed depth at tackle.

There are seven other defensive ends on the roster besides Anderson, including the recently injured Da'Quan Bowers.
Anderson has good size (6'5", 280 lbs), but even so, struggled mightily last season at Wagner College, where he managed just 20 tackles and a half-sack in 11 starts.
Nix struggled to make much of an impact last season, although he was not a starter, but did see action in all 13 Tar Heels games in 2011.
Where Nix (6'3", 295 lbs) may have an upper hand, however, is the uncertainty surrounding the durability of fellow defensive tackles Gerald McCoy and Brian Price, both of whom have combined to miss considerable playing time over the past two seasons.
Like Nix, Wade (6'1", 300 lbs) could benefit by adding depth for the oft-injured duo of McCoy and Price.
Wade played for Portland State in 2011, racking up 30 tackles and two sacks.
Of the group mentioned above, I believe Nix is the most likely of the bunch to make the final roster.
Aside from Amobi Okoye, the Bucs lack any real, consistent depth after McCoy and Price.
Roy Miller, Frank Okam and Gary Gibson are the other players Nix and Wade would be competing against for a roster spot.
Thus far, Miller has under-achieved and Okam has under-performed, so their performances this preseason will dictate whether or not they hang around for much longer.
