I'm literally on the cusp of trading him away and you guys aren't making it any easier (return is pretty nice, but I won't get into specifics). I agree JAX should be better, but that OL was literally AWFUL last year, and the team as a whole scored 7 rushing TDs. They averaged a whopping 3.3 per carry, and while the narrative of MJD falling off a cliff at 28 is convenient, I'm not sure it's completely accurate given some of the PFF advanced stats.
I think it's much more *plausible* that MJD was close to his career self (say 95%) and JAX was truly atrocious on the OL. Gerhart's going from one of the best in the league over his career in Minny to one of the worst. Their "upgrades" this year aren't anything to necessarily write home about.
I do think he'll get volume, and I think the Jags are going to try to control the ball and the clock even when trailing, so he's probably safe for ~18 carries/game on average... say 275 total on the season at maybe 3.7 conservatively, given the OL. That's still over 1,000 rushing, and he is a good receiver so another 300 or so there on 45 receptions would be nice (I don't think that's super conservative though -- he's averaged 7.8 YPR for his career again behind a MUCH better OL).
Double digit TDs I'm not sure I buy... unless the Jags take a massive step forward. Only 7 TOTAL last year rushing... maybe he gets 7-9 himself, but I don't think that's conservative. Let's say 8.
That puts him at roughly 320 touches for 1300 or so total yards and 8 TDS -- pretty nice season, but IMO there's substantial risk that team is AWFUL, the line is atrocious, and his numbers drop to barely 1,000 and 4 or 5. Just prepare accordingly.
The above is also assuming he doesn't get hurt...
this article from PFF lays out some reasons for caution with Gerhart, and they're honestly hard to argue IMO:
Despite his relative inactivity Gerhart has compiled a lengthy list of ailments, including Achilles’ tendon, shoulder, and multiple ankle, knee, and hamstring injuries – one of which cost him most of last season’s final month.Predicting injuries is slightly more reliable than scratching out a living with lotto tickets, but it does give pause when a running back has trouble holding up to a light workload, and is then ticketed for 16 games of repeated slamming into walls of humanity. And make no mistake, that is his job description in Jacksonville. Plus, his impressive 4.7 yards-per-carry average was greatly aided by not doing that very thing too often.
