I still don't trust the depth/quality at TE, WR, 0/1-Tech, and SS/Chung Understudy.
If Ben Watson is serious about un-retiring, then I would absolutely give him a call...and in the mean-time, I'd have the numbers of Jermaine Gresham & Lance Kendricks close to the phone...I might even bring Maxx Williams to Foxborough for a face-to-face and try to understand what exactly went wrong for him in Baltimore.
At WR, I would bring in Pierre Garcon for a thorough physical (he'd set a good example for our young Mr Henry too)...I'd also inquire about Michael Crabtree, Jermaine Kearse (Jete stank and all), Dontrelle Inman & possibly Richard Matthews too.
At DT, I'm not a big fan of Allen Bailey here. I'm looking for somebody more stout like...Danny Shelton. He'll be inexpensive at this stage of the off-season, he already knows the defense, and he appeared to improve after his benching. Bennie Logan's another possibility...and maybe Mo Wilkerson, if he's willing to stay inside and do the dirty work.
At SS, there's not much out there now except for maybe Johnathan Cyprien & his recovering ACL. I suppose some of the depth issue here will depend on the progress if any of ObiWan. I'm really, Really pulling for him to make the 53. Malik Gant is another possibility I suppose, but there just isn't enough of the necessary athleticism in him.
