I assumed that's what you're talking about, since you asked which of those guys is better than Tyler.
Indy is built to win right now. Why would they trade their starting PG for a rookie who is gonna go around the middle of round 1, give or take a few spots? Hill has a 57% true shooting in the NBA. Ennis had a 51% true shooting in college. This is somewhat tortured logic, but Indy traded their late lotto pick (wanna say 12 or 13) for Hill in the first place. Why do you think, after he's been a solid contributor to their team (and is only 27) that they would essentially want to reverse that trade?
Assuming Miami brings back Lebron, kind of the same deal with them. Their PG is a little less important because they have Lebron, but Chalmers is a solid player for them who can fill a role and can knock down 3's. Why would you trade that and risk a rookie PG when you're trying to win titles right now? I don't see that. Those guys aren't great, but they are solid, competent NBA PG right now. I'm far from convinced Tyler can fill that role rght now
Lance Stephenson is the fakest tough guy there is.
