The one thing we know about Emery is that he has his own unique evaluation system... he isn't going to take Mel Kiper's best rated.
I have alot of concern with taking a 6'0 285 defensive tackle. Yes he blew up the combine, but i think a 40 time is overrated for a defensive lineman. A guy with size and speed I like, but with speed only, it is a question mark.
Will Emery go undersized again on the D-line? Questionable.
Although I agree on taking the BPA, we need so much help on defense I don't know if I want a boom/bust type prospect. Some solid production at any D-line position is what I prefer, whether or not he is a combine freak.
Finally, Emery likes flexibility in an early pick. Donald is a gap-shooting DT, and that is it.
