Now that the roster has been cut to 75, the picture becomes clear on how the battles are shaping up.
The Patriots 75-man roster cuts were players I didn't expect to make the roster out of camp anyway, but the third preseason game does offer insight to how these battles may conclude. The RCB and nickel battles are pretty much decided at this point, which leaves only the Dime role up for grabs.
Battle #1: RCB
Tarell Brown will likely be starting across from Malcolm Butler in base defense, but could end up kicking inside in nickel defenses and play the slot receiver.
