Edds played Sunday, also. I know teams are constantly cutting and signing players, but it seems curious he got minutes Sunday only to be cut a few days later...though these are the Pats, and they've been known to shuffle players around depending on who they're playing (namely conference foes).
Tarp was a freakish athlete. At Sr Day last season he tested phenomenally, but as stated above, his health has always been a major red flag. People should also recall Tarp was ahead of Hunter when they were sophs battling for the starting Will spot, but of course Tarp got injured and couldn't take the spot back from Hunter.
