I mean...is this really a contest? Davis is terrifyingly good. The only players I'd definitely take over Davis are LeBron and Durant, and even with those two, only for the next year or two, tops.
Yeah. I like all 3 players, but even with Blake's playoff numbers so far there's no debate. Not to rely too heavily on the old chestnut of "Give X the team that Y has," but can you imagine Davis in Blake's place? I mean, a Paul-Redick-Barnes-Davis-Jordan starting 5 is, in my opinion, scarier than a Evans (or Holiday)-Gordon-Poindexter-Davis-Asik lineup. No one would get a shot off within 10 feet of the hoop!
But I think get_banners puts a really interesting question out there: let's play the same game with Davis at 22, Durant at 28, and LeBron at 30, and let's say we're talking about just next season. Who would you rather have? I'd still say Davis, but it's a heck of a lot closer for me.
(If you're looking for this year's stats to compare, here's Pro Basketball Reference with the 5 players: http://bkref.com/tiny/y283c )
Davis on this Clippers team this year instead of Blake ?, no way they'd be as successful. Part of Blake Griffins playoffs #'s is being hard to stop him in one given way. His skill set is too diverse.
From how he can move off the dribble, the mid range, the driving ability, finishing ability, passing/facilitating. He's a do it all type of guy and has grown since entering the league.
Davis in due time will improve but he plays exactly the same each game, he'll score 30PPG off clean up baskets on this Clippers team he wouldn't have nearly as much of those to clean up and defense would shut down his mismatch advantage on single coverage with a double team etc.
This is why basketball is not played on paper.
I think you're vastly underrating Davis and overstating Blake's game.
Griffin shoots about 40% on shots beyond 3 feet, and those shots account for about 67% of his offense.
Davis shoots about 44% on shots beyond 3 feet, accounting for 65% of his offense.
On the P&R, Davis ranked in the 84.6th percentile, while Griffin was below average (40.7th percentile) in terms of points per possession. Davis' eFG% on P&Rs was .572, while Griffin's was .467.
I think it's hard to argue Blake's offensive superiority, when Davis is more effective on both jumpers and the P&R.
