Yea, I didn't take this as "IT has to be a 6th man"
It was just confirmation he can't be your only guy. which is ok, no one can. Those teams, if they ever existed, are dead.
I think the series just made it clear Isiah isn't the number 1 guy in a trio, but I would be fine with him as 2 or 3.
My hope is Butler via trade, and then you bring in a experienced shot blocker if you can't get the third peice this off season.
I would be ok with a trade for Butler, then adding Noah on a short term (2-3 year deal) as a UFA if you strike out on Durant, depending on contract for noah(not a max, if he wants a max im out) It your starting unit looks like:
IT
bradley
butler
noah
amir
with Smart leading a bench unit, I think that's a good start on moving forward. Then you just need to upgrade one more spot with a true Superstar, and your good to go.
