Lol no he isn't
While I'll give you that Frank's not the next coming of Ricky Rubio, I just don't buy that Thornton would be transferring (+ be willing to sit out the year) if our staff had been willing to assure him that he'd be the starting PG next season -- as opposed to a guy who would be stuck competing for a starting role, and may have to split PG responsibilities with one or more players. The fact that the DT's transferring suggest to me that, at a minimum, the staff told him that he'd have to compete with Frank for a starting spot / minutes -- which, in turn, leads me to believe that they feel confident that Frank could play point. If the staff agreed with your assessment of Frank, I just don't see any scenario where they would have allowed DT to leave based on concerns about his role. From reading what the Thornton camp has been saying since the transfer, it seems pretty clear to me that DT's leaving b/c Duke's staff wasn't willing to commit to him as the unquestioned PG of the team.
