Todd Gurley is sitting at 291 touches, or about 22.3 a game. Saquon Barkley has 287 touches, or 22.0 a game. Zeke's 25.6 touches per game is higher than both of them, but not completely out of line. Part of that's just being a feature back. If we started limiting Zeke's touches, people would complain about how we're not utilizing our top 5 pick.
It's going to be interesting to see how Zeke ages, though. On one hand, he gets giant workloads and has a contact-hungry running style, on the other hand, he's been remarkably durable so far and his game's mostly built around vision and power, which is going to work a lot better at say 28 than just straight-line speed. I think if he takes care of his body, he'll be productive for a long time, even with these hard-hitting workloads in his youth. Not necessarily Emmitt Smith / Brett Favre / Jerry Rice kind of long time, cause players with that kind of durability are just once-a-generation type genetic freaks at their positions, but I could see him being a feature back till his late 20s. He could even stick around as a passing-down back for longer than that because of how good his blocking and hands are.
But that being said, it's up to Zeke to take care of himself. The end can come quick for players who rely on their natural athleticism and don't keep themselves in shape, and from what I've seen from Zeke, he often doesn't start the season in shape. That's honestly my biggest worry about him.
