An important set of numbers to highlight is Y/A rushing.
It is a cliche, but some backs get in a rhythm with more carries, and Hill is far more built for the rigors of a feature RB punishing, and to receive a volume workload. Factoring in touches Bernard will get with receptions, they may want to keep a close eye on his carries, like a pitch count in baseball.
Within the time frame noted above of the last nine game proration for Hill, 172-929 = 5.4
Since Bernard missed games 8-10, taking up his production from after the changeover to Hill as feature RB, in the last six games, 79 yards was his high, 49 yards was his next high, and he had two games with less than 20 yards. 59-234 = just under 4.0.
That is almost a yard and a half difference PER CARRY. Sure Hill broke some long runs, but if he is as talented as it appears, and it wasn't a mirage, he doesn't inexplicably regress, that may be a regular occurrence. Back to one of the original premises of potentially being able to handle a volume workload, and that helping to establish a rhythm, it could be a numbers game, and the more they feed him the ball, that increases the chance that he pops an explosive play or two of 20-30 yards. I haven't looked at splits by quarter, but he seemed like a well conditioned athlete for a 235 lb. RB, with stamina and endurance. Do any of you guys recall him huffing and puffing a lot, grabbing his knees, tapping out? I don't. So he might be the kind of back that you want to feed even more in the fourth quarter (unless they are down by a few TDs of course, game script can dictate usage), so he can take advantage of tired defenses, worn out by the pounding. Late in the game, it may be harder for a DB to make that "business decision" when he gets to the second and third level. I don't mean it simplistically, but using him more, if he is the better pounding RB than Bernard, and they may not want Dalton trying to carry the team, may be CINs best chance to win. If we realize that, Jackson must?
To sum up, if the Y/A discrepancy between Hill and Bernard continues, I could see them not stubbornly continuing to try to get Bernard some workload closer to half, but instead trying to get Hill even more involved, to take advantage of just flat out being a better pure between the tackles runner, and better tackle breaker from anywhere on the field. Bernard is obviously very dangerous in space and the open field, which aligns with his receiving skill set. If they wanted to get him 70-80 receptions (without referencing last year), he could be the receiving component of a Faulk, Westbrook, Bush, split out like a WR, just not run as much as them (especially the first two).
* I agree the 300 attempt number seems high, the 230 low, and 280 looks, if not exactly in the middle of those two, is within 25 carries of that (255 exactly in the middle of 230 and 280), about 1.5 carries per game. I think he has at least 250 carries, and won't be a surprise to me if he pushes up to the 275-280 range or higher).
