I'm not surprised by Trigg. After @Memphis Ram mentioned character concerns, I did a little research, and there seem to be substantial character concerns. Gifted athlete, but reportedly a bad person and teammate.That would do it along with his size.
The fall of Endries and Trigg are also surprising.
EDIT: Eagles picked Micah Morris with our former sixth round pick. I don't mind, actually; strikes me as a guy who has real issues with technique and would be best served losing weight.
