The one positive that runs throughout grading Alabama through eight games is defense, and that compliment can go to the Tide's bench as well.
No matter what substitutions Alabama makes, you never really see a defensive drop-off on the floor. The smallest exception might be some quickness when Carl Engstrom comes in, but his length at 7'0" helps to make up for that.
Scoring-wise, Alabama is only getting a meager 16.7 points per game from their subs, with freshmen Trevor Lacey leading the way with 6.8 points. In fact, Lacy was the offensive spark that lead Alabama to come from behind and make it a game against Georgetown. I think Lacey will make a strong push to eventually be in the starting five, especially if Randolph and Cooper don't pick it up offensively.
Lacey can score, but he's also a capable point guard, despite the fact that Alabama often uses Ben Eblen for that role.
Nick Jacobs has provided a big body down low, but he is raw and fits well at his current time contribution.
The one player I would like to see more of his Charles Hankerson Jr. He played really well against Alabama A&M in the Tide's attempt to make up for Tony Mitchell's injury. Just looking at Hankerson, you can tell he did some work in the offseason.
Through eight games, Alabama's bench is deeper than a year ago, strong on the defensive and rebounding end, but like much of the Tide team, lacks when it comes to scoring.
