It wasn't meant to be. I was merely making a case that he should be given a chance prior to being written off. The ceiling for Waiters on this team is as a 4th scoring option/defensive stopper (Thabo Sefolosha lite) or providing a spark off the bench. You are right he is a poor shooter but it's much easier to score efficently when you are getting open looks and are not the second or third scoring option. If Lebron pushes him there is no reason why Waiters couldn't get better defensively. He is pretty athletic for a two guard. At the end of the day, if he puts in the work he can change his game completely.
P.S. Miller and Allen will get plenty of time but ideally neither should log more than 15min a night.
Miller and Allen won't need to play more than 20 MPG, they essentially occupy the same role. Waiters himself only played 30 minutes a game last season, so he could be moved for someone who actually plays defense (another thing Waiters has never done) for about 15 minutes a night, while Allen and Miller split the other 33 minutes.
If the only thing positive you can say about a player is that he'll be acceptable as a rotation player if he does or improves two things he's never done, chances are he'll never be worth anything.
