Tons of things to look for.
Keeping in mind it is April and...
1) Shane McDermont, Duke Johnson, Clive Walford, Rashawn Jenkins, Ladarius Gunter, Olsen Pierre won't be playing but will be starting/playing a lot in the Fall.
2) Joe Yearby, Chad Thomas, Michael Wyche, Anthony Moten, Braxton Berrios have yet to actually practice yet and will presumably/hopefully play in the Fall.
The offense will need Olsen, Gadbois, Edwards, Scott to step up this year. On defense Kamalu, Carter, Burns, Kirby, Fig. So I'll be watching them.
