If you're not excited about the best all-around talent in the draft falling to us then you're over thinking it. We had Kevin Martin when we drafted Tyreke and I'd say we came out ahead in that equation. Not that drafting McLemore would spell the end of Tyreke in Sacramento necessarily, but if it doesn't work out then you trade the lesser talent (which is assuming we can even re-sign Evans to begin with). But making that assumption, some people here are convinced Tyreke is so incapable of running an offense that we desperately need a PG and some people are convinced that his jumpshot is so broken that he needs to be surrounded by shooters or our offense goes to pot. Well, McLemore is certainly not the former but he is the latter. Probably the best one in the draft and he also happens to be a huge threat to dunk on people and a capable defender. I'm not really committed to either line of thinking. I don't think Tyreke is a born PG, but I do think he can fill that role with a well constructed roster around him. I also think he can get his jumper to a Westbrook level of competence where it's enough of a threat that the defense has to play him honest. And regardless of position-related biases, if you have a big strong lane-attacking guard and a multi-talented bigman who can score points in bunches, a deluxe 3-and-D wing seems like an excellent third piece to me.
But this is probably just a rhetorical exercise because the odds of McLemore falling to us at #7 are slim and none. Same with Porter. I actually think there's a better chance at us getting Noel than either of those two guys because his injury is a legitimate concern and he really only helps you on one end of the court. But with McLemore, he has to bomb some workouts pretty bad for all three of Orlando, Charlotte, and Phoenix to pass on him. All of those teams need guard help and they need scoring.
