Cabrera and Devin Perry are on a similar PT trajectory. Both were rs Frosh last yr playing behind a ton of depth. Walk-on Senior Dalton Stogner and rs Soph Jordan Fieulleteau were the third stringers. Cabrera/Perry didn't outplay these third stringers so didn't get many reps last yr.
The two might be third-string this yr, but Juval Mollette is decent, Anthony Ratliff-Williams is really good and coming on strong to compete with Jordan Fieulleteau and Jordan Cunningham for two-deep. Proehl is really solid and he could even get some reps at the regular Wr spots as opposed to a-back only... so they have a bunch of competition.
But the Jordans don't seem amazing, so if the guys are athletic and fast, they have a chance to be in the 2-deep 2017, but they need to come on strong since there are serious studs arriving summer 2017.
