When you're out there and you can't give it your all, that's when injuries are more likely to happen. Walton was favoring his other ankle, he couldn't evade defenders, he had no burst to get himself away from defenders or out of harms way. You can't tell me all those things didn't factor until his ultimate injury. So yeah, I think this is on the coaches. They got him injured in garbage time to begin with when the backups should have been getting reps. Then they exacerbated his injury last week by having him in the game late when he shouldn't have been. The mismanaged him and drove him into the ground.
