Obviously you can't base your entire analysis on One vs Ones, and a lot of the top end talent aren't here. But in these videos, there a few guys that definitely stood out, both good and bad.
The Good:
Aaron Robinson - very physical, in good position almost every play
DJ Daniel - didn't look as physical as Robinson, but was in the right position most every play
Cameron Bynum - a caveat that he did get burned a time or two, but he was in the correct position more often than not and I like his physicality
The Bad:
Shawn Davis - he got owned basically every clip I saw. Granted he's a safety, but he looked really bad.
Robert Rochell - very bad foot work, played catch up a lot
Tre Brown - he seemed to get overpowered a few clips and got out of position a bit. Seemed grabby too.
Again, you can't make your final decision based on this, but it's worth something I think. Definitely reaffirms my fondness of Aaron Robinson.
As an aside, Shi Smith and Marquez Stevenson are SUPER quick and twitchy. I really like both of these guys at WR in the mid-late rounds. Josh Palmer looked good too.
