Esukpa has 22 games under his belt. Equivalent of 2 full seasons. Not bad, but not great for a grad transfer.
Williams 26 games, so two full 13-game seasons. Again, for a grad transfer, it's good but not great. Valuable for sure.
Katoa has 11 games, but 3 of them he basically didn't touch the ball.
Allgeier has 4 games.
Inexperienced was the wrong word to describe everyone, but they don't individually have tons of it. Two grad transfers who each had two season's worth of games, and then just a few more after that. It's still not ideal. Not one person on the list has ever made it to 100 carries. Not one person has ever had 500 yds rushing. Two of them are coming off injuries. None of them were ever the featured guy.
Just saying there are a ton of question marks. The only good thing is that in a year where there's no clear #1 or 2, you combat it by having a few guys who can be expected to contribute. Which is especially helpful when factoring the injuries.
