Every team already had a bunch of chances when their rosters weren't nearly as restrictive.
I've got news for you. A 7th round pick making the practice squad is a win for that player. Honestly, there is no such thing as a 7th round bust.
Who does he replace? Full Monty, Cohen or Davis. We kept a 3RB and a FB last year but Patterson is taking on that extra back roll and takes away Whytes best chance of making the roster as primary returner. I'm not saying he can't make a play day roster but he's the guy you can sneak through waivers unless he gets showcased in the pre.
Would you rather risk Emanuel Hall, Javon Wims, Denmark, Shelly? They can't all make the 53 and more than one will ned to sneak onto the PS plus Whyte would clearly be the 4th string RB. I'd have no issue with him making the 53 but in my opinion he sticks around on the PS because other teams aren't putting him on their opening day rosters because more complete backs will also be cut by other teams and he chooses to stay. Obviously things will change between now and Sept but that's my current opinion.
