This is rough to handicap because all of the guys you mentioned appear to be at least two to three years away from making an impact at the NHL level. However, with that said, I don't think Jenner is a great option in a league that primarily rewards goals. Plus, I'm also not sold on Jack Campbell.
Instead of dumping him outright, any shot you could trade Jenner?
