He is not a center, and he would be playing the 4. However we already have Polley who keeps improving and Sid now being eligible. If Akok were to join next semester he would certainly add more competition for the front court, but I am not sure if he will have a big impact on the court this year.
If you compare him to Polley:
Polley is taller than Akok.
Polley is a career 40% 3 pt shooter, that would be hard to match for Akok in is first year in college.
Polley has a year plus worth of practice and game experience working with his current teammates.
Polley is currently leading the team in blocks.
Getting Akok to come to UConn next semester would be great for UConn. It would energize UConn's recruiting, it would probably get the attention of other recruits, and if Akok can get to the NBA it would be a great recruiting point for the future.
However I don't think that he will have a big impact during games this year. This speaks more to Polley's development than anything else.
This is a well thought out post but I think it's a forest for the trees thing. Our most glaring weakness right now is that we play pressure man and have no one to clean up mistakes at the rim. Polley's leading the team in blocks merely proves the point.
If he comes and can block shots, he'll get run.
