He was picked at the end of the third round....in an incredibly deep RB class. He was the 5th guy picked, and 6 more were selected by the end of the 4th round. Pretty clear teams were waiting on runners, likely at least in part because of the depth of the class and probably also because the league has devalued the position the last decade-ish.
I'm not even that big of a fan, but what round he was selected in this particular draft probably isn't as indicative as it might be most years (plus it's not like teams don't draft guys that they view as starters in the third round anyway.).
Certainly, he could totally bomb. So could Jeanty, or Hampton, or Henderson. His 40 was his 40. His game tape is also his game tape. He went to a near perfect scheme for his strengths with a coaching staff in place that's ready, willing, and horny to play "dinosaur ball."
He just seems like the perfect fit for the Steelers and I don't respect Warren the way many seem to. If Warren couldn't take the job from Najee (3.9 career ypc) then I definitely don't see him taking it from Kaleb Johnson.
Warren has some juice, there is no real denying that if you watch him run. However...he puts it on the ground. Guy is in, what, year three or four now and local beats say that last year he was still carrying around a water filled football everywhere at the facility. Mike Tomlin detests turnovers, and I would happily wager someone else's money that it's the main reason Warren wasn't given more run as the "1a" to Naj's "1b."
He's also gotten banged up a pretty decent bit for a guy who isn't the "go to" so far, which limited his availability/effectiveness when he was dealing with those. That'd be a pretty big concern for me if I were a Warren Truther. I think the Steelers intend to give him a shot to be the lead guy, but it's easy for me (and likely them) to envision him playing well until he gets a nagging soft tissue injury, or two, and see his productivity drop/the rookie get more run after that. If that happens, I don't see Kenneth Gainwell being inserted as the presumptive starter long-term, so Johnson's path to meaningful carries is probably pretty broad.
