That gif almost makes it ok with me if they take him at #4. I'm currently in a anyone-but-Tannehill-at-#4 mood.
Sounds like he ran between high 4.4 to low 4.5. Coming 2 months off a knee scope, and going at 70-80%, ain't too bad. He was mad though, thinks he could get near or at 4.3
But "football" speed, he wouldn't be at that. There are times he was "ran down." Sure, it was after 50-60 yards, and partially because he wanted to hit one more person going into the endzone, but yeah, top end speed isn't his game.
