I saw him play against Texas Tech last season. I liked him, but at the time I was far more interested in the guard matchup of Morandais vs. Emmett. Sufficed to say, considering I was looking at guards, and still noticed Harrison, but thought he'd be drafted before we had a chance, he's a good pick at the end of the 1st round.
On a related note, we should bring Morandais into camp. He's a good shooter, is quick, and seems fundamentally sound.
You guys are way too negative. I mean, it's not like you picked Frederic Weiss! (grumble)
Pretty fair for a 29 pick though being stuck with him 3 years if he flops isn't great.
