I think he's a character guy who's just been unlucky and very disappointed at where his bad luck ended up getting him drafted.

Chris Canty DE Virginia 6’7 290

Chris Canty is very accomplished both on and off the field. Canty became a full time starter as a sophomore, and he took full advantage, racking up All ACC honors with 86 tackles. As a junior, he was once again an All ACC performer with an unheard of 104 tackles for a defensive lineman. He also added 4 sacks and 12 tackles for loss. In just four games as a senior, Canty had 30 tackles, including 7 for loss. Canty has been named a team captain, all academic ACC, and graduated after his junior season with a degree in African American studies.
He has a solid background as his mom has been a methodist minister for 20 years.
Also, I've read where Al Groh recommended him as a true character guy to Parcells.
