The thing most people don't seem to realise is that you can't JUST get a rim protector. You need to get a rim protector who is skilled enough overall that you can afford to play him starters minutes...because there is no use in a rim protector who plays 5 minutes a game.
How many rim protectors are there in this league who are also starting caliber players?
This is where you can remove guys like Biyombo from the list.
And I get the feeling that you're severely underrating the 2013-2014 Spurs. They're not just some well-coached team of role players. That team still had Parker, Duncan, Ginobili (who turns it on exclusively for the playoffs) and the 2015 DPOY in Leonard. I don't think we have a player on the level of those 4.
So you don't think we have a player of the caliber of a 38 year old Ginobili, a 38 year old Duncan, or a 34 year old Parker?
I'd like to hear somebody explain what Parker does better than Isaiah Thomas, because I've got nothin'.
Score? Nope.
Pass? Nope.
Defend? Nope (Parker was one of the few guys with a worse Defensive RPM than Thomas)
Rebound? Nope
The answer is, nothing. There is nothing Parker does better than Thomas other than simply being a few inches taller.
I think we have a number of guys who are better players than Ginobilli is right now. Pretty much everybody except Wallace and Pressey.
Duncan and Leonard present tougher challenges.
