Eblen could actually see his time rise this year. He was an enormous liability last year because when he was out there it 4 on 5 at the offensive side of the court. IF, and it is a big if, these new guys can provide solid offensive production then Releford won't have to be as much of a scoring option and Eblen can give him longer breaks, and keep him fresher.
Also, I wouldn't be surprised to see Bama use a smaller lineup at times. As much zone as Grant has been willing to use, they could go with a lineup like: Releford, Lacey, Randolph or Cooper, Mitchell, and Green.
Randolph and Cooper bring length that can be effective in a zone where they would otherwise be a mismatch in man-to-man vs. bigger interior guys.
