I think this trade doesn't make sense for Indy, because if they trade Paul George they are asking at least a very good young player + a high draft pick. Nor for us, as we can't start George as a PF (he won't like it at all) and risk losing him for the Lakers after one year. I wouldn't give Indiana a Brooklyn pick + Brown in exchange for what might be just a rental. Your IFs are too big to overcome.
The "logical" trade with Indy is Thomas for Turner, as long as we'd pick Fultz and signed Hayward as a free agent. This will allow them to convince George to stay (win now mode) and we will keep good in offense (Hayward + Fultz + Turner instead of IT), improve A LOT in defense and extend Bradley + Smart for long.
