Too soon to tell for sure, someone could come on strong their senior year. If so, it should become clear in the next few weeks as these seniors get further into their season.
Newton, or someone else (?) gives your more imediate depth. Right now you got Stephens, and a FR. in Bray. The next year you have a SO. Bray, and 1 or 2 FR.
Im not sold on Stephens and Bray as being the only options next year.
