Nice threat topic, Az. I completely agree with your structure.
Phase 3 may not have much for us this year.
A QB, certainly. Flutie or another like him.
Maybe a WR, but probably of the JAG TC-bait variety (assuming we can even find one) with an eye to the kicking game. Tim Dwight-like.
Maybe a veteran LB in the Bryan Cox, Roman Phifer, Chad Brown mold.
Long shot for a veteran OC for depth... but Hochstein is absolutely adequate.
Other than that... probably not much.
Remember we got Grammatica, Caldwell, Jones and Mitchell in Phase 1, and in any other year those would be Phase 3 players. I actually think the 80-man roster is pretty loaded and very deep.
And, as mentioned, the Phase 3 talent pool is very thin this year. Even slimmer pickin's than usual, and not a strong likelihood of finding players who'll be competitive in terms of experience, size and speed.
