One other piece of the analysis:
While not being used as much as a running QB, Thompson fumbled 3x and lost 1.
1 fumble per 18 carries. 1 lost per 55 carries.
Adrian fumbled 7 times and lost 3.
1 fumble per 19 carries. 1 lost per 44 carries.
Fumbling at a similar rate, but Adrian strung together 4 years with the other 3 all being a little worse than last year.
Thompson only had the one year with significant carries.
Adrian was our bell cow “top rusher,” and if you had a regular bell cow RB, he wouldn’t last fumbling as often as Adrian.
Ball security for Casey will be extremely important if he wants to stay in good graces with the fans.
I kinda like what I see from Casey, but he still has a lot to prove here before I’m sold on what he can be for us.
