Fesenko has always intrigued me. He is a huge body and a good athlete, and the little I have seen him play, he has impressed me with at least some basketball sense.
If, they can get him for the vet minimum, I think he would be an excellent option to bring in as the 3rd or 4th (depending on how reliable the guys in front of him are) center.
I think he is the type of guy Danny would like to target for those end of the bench positions rather than rookies. He has enough experience under his belt to be able to step in when needed, and could be getting to that point where he is ready to step to the next level.
