The Baylor quarterback appeared on Tuesday's edition of "The Dan Patrick Show" and said he expects to run a sub-4.5 second 40-yard dash during the combine.
Lombardi: Combine captivation
Griffin declined to take the bait when asked if he could rip off a time in the 4.3-second range. He did say he's been clocked at less than 4.4 before, however, and he said "there's a possibility" he could do it again at Lucas Oil Stadium.
"We thought it would be fair to everybody involved -- to all the guys coming out of Baylor -- to have all the scouts there to watch instead of having them split between me and Andrew," Griffin said.
"I have no doubt if they had stayed the same and neither of us moved, they would move it," Griffin added. "But we decided to be active and move ours ahead just to be the bigger men and not make it a big issue."
"I try not to expect anything," Griffin said. "They haven't announced who they're picking first yet. So if I get that meeting, I'll cherish that."
