I don't want to belabor the Harris part, but on the "I've seen him take over games", Harris only has 5 career games of 100 or more rushing yards. He downright dominated the Browns back in 2022, with 188 rushing yards on 28 carries, but that's really about it in terms of games he really "dominated". That doesn't mean he doesn't have other good games, but is putting up 105 yards on 26 carries a particularly notable game? Not really.
He only has 3 games of putting up above a 5.0 yards/carry and 100 yards. He has more games averaging below 3 yards per carry (14) than games of averaging more than 5 yards per carry (8), and about 60% of his games fall below 4.0 yards/carry (32 of 54). I just simply do not see any sort of performance he has given, outside of that monster game against the Browns 3 seasons ago, that says anything but "he's just a volume back". He has far more "14 carries for 37 yards" type of performances than any sort of performances that you can call dominant. Maybe he shows glimpses where he takes over for a quarter, sure, but I figure most players can do that.
For comparison, Warren has 12 performances of 5.0 yards/carry or better, and even if you take out the sub-50 yard games, he's still at 6 games of things like "11 carries for 88 yards" or "15 carries for 101 yards". And that's with Warren playing a season less than Harris.
The Steelers have an absolutely awful track record with 1sts in the last 10 years. They're lucky as hell Watt became a monster because their 1st rounders have been horrid. Jones, Pickett, Harris, Bush, Edmunds and Burns are all just bad picks.
The Steelers have drafted great in the 2nd and 3rd rounds, but man they have whiffed on so many 1sts and I'm not seeing why I should think Jones will be any different. Thankfully Fautanu looks good, but he just needs to stay healthy.
