Adrenaline is a huge factor in this also. Don't think he will be able to maintain 96 throughout the entire season. Probably a 90-93 guy touching mid to upper a handful of times a season. But, he was throwing considerably harder against FAU this weekend when he came in the game at the beginning with less control and I think that's the adrenaline of his first conference home appearance against a strong hitting ball club. Also, against Rice on the road with a lead could cause Kellog to have a little extra adrenaline and have a little extra on his ball.
Aroldis Chapman averaged over 101 MPH in his first two appearances, but ended the year in the mid 99 average MPH.
STILL, if he's hitting 96 every now and then as a freshman it's going to be scary to see what Kellog can do over the course of a 3 year career if he gets the correct weight training and stays healthy. Someone needed to step up with the early departure of Dayton and Zach graduating. Looks like a few people have!
