Agreed but I think CBS should wait a few more games before making the switch. It'll be easier for Hayward to accept if he feels CBS has given the new starting lineup a fair shot.
I like Hayward off the bench instead of Tatum and Brown because Hayward has the most well-rounded game. Shot-creation, ball-handling, playmaking ability. Hayward is the one best suited to lead a less offensively 2nd unit lineup.
Hayward should be to Boston what Ginobili was to San Antonio.
