SI's Don Banks has pegged Carson Butler as one of the top 10 players to watch as possible undrafted FA's who could become legit NFL players (there has to be a more concise way to say that).

5. Carson Butler, TE, Michigan -- Only 21, the Wolverines junior opted for the draft in part because his role in Michigan's offense disappeared when head coach Rich Rodriguez brought the spread offense to Ann Arbor. Butler is a bit of a project for a team that can afford to take its time with him, but he's 6-5, 257 pounds, with an arm-span of more than seven feet. His 4.6 speed should also prove tempting, because it's faster than your typical NFL tight end.
I'm not really sure what to think about this, so was curious what other people's reactions were. And I'm not much on the interwebs posting, so my bad if i did this wrong.
