I feel like they won't keep EJ, Cassell, and Tyrod.
They'll keep Simms as the #3, and then two of the other ones.
My gut feeling is that it will be EJ, Tyrod, and Simms. Cassell gets cut at the last round.
IMO
My guess is Gresham if they really want to upgrade the position. He's the most well rounded in the top tier of FA TE's, in my opinion. He's a solid blocker in the run game (which will be important to this coaching staff) and runs decent routes for a big man.
That is close to the tag number for a DE this year, which is pretty amazing.
And he did play tough against the run this year, especially the second half of the season. If he isn't a 3 down DE right now, he's as close as you can get to it.
