there are some slow mfers here. 40 times from the RB group:

Dalvin Cook, FSU: 4.50
- not good at all.

Christian McCaffrey: 4.49
- average for his size (200 pounds). his second 40 was 4.59.

Alvin Kamara, Tennessee: 4.50
- considering he's also barely 200 pounds, nothing special. although he never showed breakaway speed in college; he's more shifty than anything.

Leonard Fournette, LSU: 4.51
- actually the better than everyone above him because he ran at 240 pounds.

Wayne Gallman, Clemson: 4.57
Kareem Hunt, Toledo: 4.62
James Conner, Pitt: 4.66
Samaje Perine, Oklahoma: 4.66
Corey Clement, Wisconsin: 4.68

- at least Perine and Conner are 230+. Clement's and Hunt's times are abysmal.

Joe Williams, Utah: 4.40
- helped himself a lot today among a sea of plodders.
