Two big question marks:
1. Secondary - we will most definitely lose Artie. Does Corn jump as well? Even if he doesn't, that will leave us only one returning starter at corner and we don't have talent backfilled at the position
2. Offensive line - should we expect the unit to get a major boost? I know we are redshirting a few guys, but as of right now, this is it. Offensive line is not a priority for 2016 recruiting class
I agree regarding the CB position although I do believe Sheldrick Redwine and Michael Jackson could be solid with a good coach. Safety will be solid with Rayshawn Jenkins, Jamal Carter and Jaquan Johnson all talented and experienced.
These starters on the offensive line are young (3 SO's and 1 JR) and with another year could be very solid. There will be 15 returning scholarship offensive linemen on this roster in the spring. Thats a 3 deep of offensive lineman, those guys simply need to be coached up.
