I watched the first practice today and from what I saw and heard come from Mike Mayock and Charles Davis, here are those who stood out and those who struggled. Unfortunately the NFL Network spent like 20 minutes talking about two QB's who probably will never play QB in the NFL (Kellen Moore and Russell Wilson.
Kendall Reyes DT UConn
Kevin Zeitler OG Wisconsin---actually handled Ta'Amu of Washington pretty well in one on ones.
Vinny Curry DE/OLB Marshall--showed explosive pass rush ability and appeared stronger than most thought
Marvin Jones WR Cal looked to be best at route running.
DeVier Posey---looks fluid and caught everything that was thrown at him.
Johnnie Troutman OG Penn State
Keleche Osemele OT/OG ----------struggled in pass blocking. Mayock commented that he didnt have the feet to play tackle in the NFL.
Mike Adams OT Ohio State---struggled early on in pass blocking but showed better as the day went on. Solid in run blocking. Vinny Curry ate him up a few times.
Marvin McNutt----had some drops (very uncharacteristic of him).
Alfonzo Dennard---got beat deep by Marvin Jones
