IMO, it just doesn't make sense for him to go to Cincinnati, and this must be a credit to the salesmanship of Mick Cronin.
They earlier signed a much higher rated juco power forward John Williamson, who plays the exact same kind of game as Sikes.

They also have a juco All American Cedric McGowan (former teammate of Will Franklin) who started 29 of 30 games as a power forward for Cincinnati last season (the only game he didn't start was senior day when he relinquished he starting position). He plays the same position as Sikes and Williamson, too.
And they have another returning power forward type, 6'9", 225 lb. Ronald Allen, a transfer from Xavier of New Orleans who was their top sub at the forward position last year.
So good luck Marcus. You are joining a rebuilding team (they lost their coach and their top 5 scorers), in the Big East, where Cincinnati finished 8-8 (8th place) last year, and will not be projected to be any higher this year. And yet, they appear to have 2 returning seniors and another highly rated recruit playing the same position in front of Sikes. I hope they find playing time for him.
