Not really, they already have Klay/Draymond handle the ball on offense an awful lot compared other PFs/SGs. Plus he's a great PG, even if he does have the propensity for really dumb turnovers at times. Plenty of PGs do that.
Conley would certainly be an upgrade for the team, though I'm curious how he'd mesh with a system so unlike what he's played in so far. (fine eventually I'm sure)
