I kinda see two different versions of "mobile" QBs in the NFL right now
True running QBs - big, tough, and offense uses designed QB runs often
Cam Newton
Josh Allen
Lamar Jackson
Dak Prescott
Mobile - pass-first QB, elusive in open field or pocket, regularly adds rush yards when plays breakdown, avoids hits when possible
Baker Mayfield
Russell Wilson
Kyler Murray
Patrick Mahomes
Aaron Rogers
Joe Burrow
Carson Wentz
Deshaun Watson
Matthew Stafford
Ryan Fitzpatrick
Sam Darnold
Seems like nearly all the younger QBs coming into the league are pretty mobile these days. The true running QBs are more rare IMO, and seem to get banged up more often (Lamar Jackson is the only one on my list above that's been able to remain healthy so far). The way I see it, we seem to use Sanders as if his running ability is primary, and his passing is secondary. Not only does that bring down our ceiling, it actually hurts his NFL chances unless a team wants him to play a role similar to Taysom Hill....and that's a shame, because I think his arm is pretty good.
