why trade Irving at all? not seeing the point. even if the C's win the title, having Kyrie and Hayward added to the active roster next year makes this an even better team.
who starts/who finishes the games? keep players egos in check?
Cap issues. keep most or all of Smart, Rozier, Morris, Baynes or pay Kyrie 35 million a season?
I don't think it will be as easy as you think
It's as easy as can be. You keep the cornerstone players and let ancillary role players get overpaid elsewhere.
See Evan Turner:
