Kris Jenkins runs 4.91 40

No idea, he weighed in at 257 which is 10 lbs lighter than his listed weight. Usually, if you lose weight for the combine, you want to do the events to make yourself faster. Did he get sick? 

Most of the time, a prospect try to gain weight to show themselves that they're big enough for the position and opt out of combine workout so they can workout at pro day when they lose weight. 

JH nor BM ran which usually means they'll run at their pro day where you get a much more favorable time I believe it's .15 faster hand timed. The reason you wait is because you think you require the quicker time.

Dallas Turner ran a 4.46(!!) and he was held mostly in check in the Rose Bowl. Our O-line probably underrated this season.
