Ok..let me give you some stats:
With Frank on the floor, against major opponents:
Our scoring defense has improved by 5 pts per game
Our FG% has increased by 2%
Our 3 Pt FG% has increased by 5%
Our assists have increased by .8 per game
Our TOs have fallen by .8 per game
Opponent FG% has dropped by 4%
Opponent 3 Pt Fg% has fallen by 5%
Opponent steals have fallen by .9 per game.
This doesn't mean the team is good by any stretch. It simply means that the team is less bad now that Frank is back. Right now we are a mediocre team. Full stop.
If you want to replace Frank with Carey, that is fine but the numbers don't agree with you.
However, turning the argument on its head, it is a small sample size and, of course, there is always the unknown that cannot be quantified.
JC starts and begins to play much better than what he showed earlier in the season...
If that were to happen and Frank were to continue at his current level of play, then we would clearly be a better team with JC at the helm rather than FH...
If Frank has not improved by the start of ACC play then that gamble is probably worth it as the team cannot afford to wait until the middle of the ACC season for Frank to be "back". That would be too late.
BTW, I responded to you with this dissertation because you are a poster worth answering. Therefore, any debate is welcome and not considered argumentative.
