That team had no other primary scorer. Rudy was the closest thing they had. His role on that team was to be the go-to guy. He's not a #1 option which is why his %s were sub-par (42% for that series which in all honesty isn't that bad).
You're acting like they played a scrub ass team when they lost in the 1st round. They lost to the Clippers in a tight 7 game series. And the year before when they beat the Clippers Blake was hurt during the series. They didn't lose because he couldn't adjust to not being the man. They lost because they weren't the better team and OJ Mayo played like complete shit.
I'm questioning whether or not you were actually a Memphis fan like you say. You seem to not be aware of who Zach Randolph is. I'll educate you. He was the guy on those Memphis teams better than Rudy Gay. A go-to scorer.
Now, let's look at something.
Year 1- Make playoffs, beat the number 1 seed, 60+ win Spurs in round 1. Lose in 6 in round 2 to OKC.
Year 2- Make playoffs, lose to the Clippers in round 1, who then get mauled by the Spurs in round 2 in 4 straight
Year 3- Make playoffs, and this time get all the way to the WCF.
Guess what the commonality between year 1 and 3? No Rudy Gay. In year 1, he was hurt, and in year 3, he was traded. Year 2, the year he was healthy and still on the team, bounced by a Clippers THAT THEY THEN BEAT THE VERY NEXT YEAR.
Meanwhile, literally the very game after Gay leaves Toronto, they look like a legitimate playoff team. The ball moves better. Do you think Toronto's coach just had an epiphany after Rudy Gay left and totally changed the offense? Or do you think Rudy Gay was the one changing the offense, for the worse, on his own?
Rudy Gay does not have to be the man. Rudy Gay wants to be the man, and is incapable of being it.
