Honestly I don't know why anyone is concerning themselves with this(and I'm not talking about just you, twitter freaked out). He isn't gonna come out and say he is looking to replace Mitch with someone else. Just a standard non-answer answer From him
he didn't even really commit, a reporter asked him "is the plan to have Mitch as the starter?" And he replied "yes it's the plan". Plans change, just ask Mike Glennon
