Not to bash Felix, but I'm not sure what you mean by how he's been used? The kid got 10 minutes each game against FDU, Fordham, and Long Beach State. Got a total of 1 point. I get that he didn't play against Butler and Villanova. And he had limited minutes against SHU and Providence. But in any sport, you have to take advantage of the opportunities that are given to you. I do expect he'll get a few more minutes as the season progresses, but I'm not really sure how Lavin can give minutes to a guard with an inability to score.
I dont disagree that he felix hasn't earned more minutes. But I'm not looking at it objectively, his adadvisor is Diallos advisor, and I've heard he isn't pleased with how the redshirt was burnt last season and how he's been used inconsistently this season.
As a basketball observer I agree with you that Lavin has given felix repeated opportunities, but his skill set doesn't warrant a full time role.
