I've googled him since and am almost ashamed that I didn't know who he was, but the truth is I didn't. I don't know, maybe I've heard of him and simply forgot...I don't typically retain what little LA Rams information I receive (through only the most general of NFL media consumption).
Anyway, Eric basically said he's the best player in the NFL. He said he's like JJ Watt, but that JJ Watt blows assignments leaving holes wide open (when he's not blowing assignments getting tackles for losses or sacks), while Donald is every bit, if not more, disruptive but does so within the scheme, always getting back to his spot, and is going to be a superstar in the league for years to come. He said if Bills fans don't know who he is, they should find out.
The host commented that this guy (that I don't know) was the best rated player by PFF for all of last year (as a second year player), and that he is the highest rated player by PFF so far this year through 4 games.
So yea...Aaron Donald...apparently #99 for the Rams is going to be tough on Sunday...
