David DeCastro and Kevin Zeitler are the only players to beat all three metrics. If I had to put money on who I thought would have the smoothest transition into an NFL starting spot, I'd put it on these two guys. Zeitler could also play center in the NFL, and both Zeitler and DeCastro also beat the 20-yard shuttle time for centers.
If we resign Spencer and sign a CB or two in FA. I wouldn't have a problem in getting DeCastro and Zeitler in round one and 2.
