I managed to catch a few minutes of the combine today. I was really impressed with Iupati in the 3 cone although I haven't seen a time. He looked flexible. His bench press was less awesome (26 or 27) although I think his 40 speed was acceptable (under 5.3 iirc).
Bulaga was interviewed and came across fairly well. Smart guy though I found it annoying when the reporter's kept going on about it.
Bruce Campbell and Trent Williams both ran sub 5.0 and a te named Dickerson ran a 4.40 (to go with 24 benchpresses).
I got my numbers off nfl.com's combine page.
