You're arguing that a mid-range game is useless and trying to use stats to back your argument. You're sounding like you've never played basketball

If all you can do is slash and shoot 3's, you become MUCH EASIER to defend. Even Lebron with how special he is physically had to develop some sort of mid range game.

If that's all it took, then Jordan would NEVER win a ring. Him developing his mid-range game is what made him as unstoppable as he is. It wasn't him shooting a lot of 3's. It was because you had to respect the jumper, which combined with his quickness made him the nightmare that he was

It's what makes Carmelo Anthony a nightmare to guard. It's what got Dwyane Wade a title. It's one of the reasons why Durant is so impossible to defend. Grant Hill was a GREAT player, and he barely ever shot 3's. It was because of his mid-range game combined with his ability to slash.

It's the biggest difference between CP3/D.Williams and Rondo. If Rondo had a mid-range game he'd be the best PG in the league...because he doesn't it's way easier to defend him (and this is coming from a Rondo hater)

Going to Harden, the reason he's balling like he did was
A. He wasn't the focal point of the offense, so the defense had to play him one on one instead of doubling him like they would have to do to Durant and occasionally Westbrook
B. He's catching teams off-guard early in the season.

You honestly think him being the #1 option that teams are gonna let him get to the rim that easily? He's gonna have to break down the defense and hit some step back jumpers, and HAVE a mid-range game because he's not gonna get THAT many 3's, and he's not gonna get to the rim easy when teams catch on (which they will)

To say that a mid-range game isn't needed when Michael Jordan is the easiest evidence to disprove that point is crazy. Even on a basic level, ask anyone at the park, or anyone that's played ball...the cats with the mid-range game and the quick first step beat the slashers and 3 point shooters every time.
