My only concern is the depth. Asking Young / Sweat to play 80% of the snaps is bad for business. To ask Smith-Williams or Toohill to come into the game and not be targeted could be a dicey situation as well. Having a guy like Kerrigan who can play pass rushing downs and in the 'knock knock' situation Sweat or Young goes down you keep a certain level of ability.
That said, Smith Williams or Toohill may be able to fill in but similar to our depth at RB and at TE, while we feel very comfortable in the starters, what's behind them is a question mark.
