Lamar doesn't run the ball 300 times a year but he has been around 150 carries a year in his career. Combine that with hits in the pocket and there is certainly a decent amount of wear and tear. I don't suspect he's going to fall off a cliff like RBs do at age 30 but to think he won't see some decline in his speed and elusiveness over the next few years is being naïve.
My previous post discusses systems. I truthfully don't know what that would be. What are Lamar's best attributes? Accuracy on short passes and timing routes? Not really. Deep ball accuracy? He's ok with the deep ball but inconsistent at times. Are we going to put him into a drop back passing system? That wouldn't make any sense. I literally don't know where we go from here.
If we decide to move forward with Jackson, cool but what is the organization going to do to help him flourish?
On a numbers basis Lamar deals with pressure about 80-100 times less per season than the most pressured quarterbacks (Mahomes and Allen are almost always at the top of the list.)
If you compare Lamar to someone like Allen then he compares very favorably in terms of opportunity for hits. Compared to Mahomes Lamar is open to hits a bit more often, but its not a huge difference.
example: 2020, Allen had 280 pressures and 86 rushes. Mahomes had 270 pressures and 28 rushes. Lamar had 194 pressures and 129 rushes. These numbers are unlikely to be drastically different this year over a full season, as they're all on pace for roughly the same usage and pressure.
So I don't think it's true that because Lamar runs the ball often, he's more prone to injury, especially because he tends to do a good job of controlling his hits when he runs.
In terms of playing to his strengths, some of his accuracy numbers don't entirely make sense. For example, he's improved by 7% on midrange balls this year, and he's been one of the best in the league on them (10-19 yards target depth.) But his deep ball accuracy since Bateman went out has been god awful. I don't feel like a naturally inaccurate thrower would be money at 15 yarders, and then forget how to throw a football because the target was 10 yards farther downfield.
There is probably a small sample size caveat for all of this, but not having been exposed to much of this data before, it's really hard to grasp what qualifies as a sufficient sample size.
