As I've said repeatedly here, the issue for running QB's is not the frequency of injuries, it's the effect of injuries on their ability to run at an elite level. RB is a much more physically demanding position than QB, which is why RB's have the shortest careers, and only kickers have longer careers than QB's. There is no disputing that, so I won't bother to post the evidence again.I know none of Jackson's injuries have been "serious", but hell, even an ACL isn't THAT serious now days. Just a bump in the road, compared to a concussion or throwing arm injury. I'm a living example of what amazing things they can due surgically. The changes I've seen myself in just the last 20 years in the vascular/cardiac area is simply STUNNING. Want keeps me off the Lamar bandwagon are the simple injuries that cost you games like sprains, dislocations, and bruises, plus the long term wear and tear that vast shorten the careers of even great QB's like Newton and Young
RB's wear out quickly. Running QB's also lose the ability to run quickly. But a passing QB can play through injuries much more readily than an RB can.
While there is no question that a QB that can run effectively as well as pass effectively can be dominant, as a true running QB puts immense pressure on a defense and that pressure also opens up the passing game. That's why we saw Cam Newton and Lamar Jackson earn MVPs.
But like RB's, those running QB's inevitably lose that elite running ability through cumulative injury, which also degrades their effectiveness as a passer. There's nothing saying that (say) Lamar's evolution as a passer can't compensate for the inevitable erosion of his rushing skills, but that's a difficult transition because the defenses will become more effective as his threat of running diminishes.
We saw Mahomes shrug off injuries last year and win another Superbowl because his rushing skills are nice to have but not central to his success. Meanwhile Lamar couldn't even get on the field.
Again the issue is not that RB's get injured more than QB's. Everyone gets injured in the NFL except (maybe) kickers. But passing QB's can play through injuries better than any other position. But QB's rushing effectiveness is much more seriously affected by injuries, and diminishes their passing effectiveness as well as the pressure on defenses lessens.
I do think that an NFL team could be long term effective committing to a running-QB-based offense and win on great young QBs first contracts. But the team would need to commit to carrying several such QB's and keep a recruiting pipeline going as colleges do. But paying a running QB big bucks after their first contract is a very dubious proposition -- as Lamar is discovering.
