Al Jefferson has never had a season where his Wins Shares are over 8. Marc Gasol topped 11 last year, in a stat where 10 Win Shares is considered a dominant season.
We can go back on forth on this, because I don't believe in win shares at all. But given that, Jefferson plays on worse teams, so his WS will always be lower. Also, George Hill had a 9.7 win share last season, so I guess he had a top 5 PG year and really close to a "dominant season". There isn't a guy in the top 20 in WS that was on a sub .500 team. So I guess every guy on one of those teams just suck.
He was second in the league in D-Win Shares too. The reason that Memphis is so good at D is because Marc is anchoring the middle.
Memphis had 4 guys in the top 15 in that category. It could be because them play a great defensive system that pumps those guys numbers up. But if you want to make a case that Zach Randolph is top 10 defender and the best defensive PF in the league last year, that's your right.
On offense it's the very essence of who Gasol is compared to Al. Gasol plays in the high post and is a distributor-the offense runs through him. Marc is a superior passer, thus his Ast Rate last year was close to 20% and was nearly identical to his Usage Rate. Big Al is a black hole. His usage rate is exceedingly high for a player of his caliber(25%), does not pass the ball out of the block. Also taking 16 shots a game to score 17 is inefficent, especially considering how close to the basket he is(and also doesn't get to the line as a big man). Marc-taking seven less shots, doubles Als FTA,
They have different roles on offense and you are skewing the numbers. Jefferson is the primary offensive option. Gasol has always been 2nd or 3rd. Gasol is a better passer, but his assist numbers has never been far and away better than Jefferson. Plus he turns it over more. Yes, Jefferson takes 16 shots to get 18, but Gasol takes 11 to get 14. How much better is that really?
Al is notoriously terrible on defense, one of the major reasons his teams are .500 at best. A one way center with no defensive impact is pretty invaluable as a player-which is why Al has been traded twice and is now signed to the Bobcats.
I can't debate that he is a bad defender. But his team's failures can't all be put on him. He has played in bad situations, under horrible coaches. Plus, he is not a Center. He is a PF and has had to play out of position out of desperate team need.
Gasol, now free of Rudy Gay, is an All-NBA player, an All-Star, a starter for the second best international team, took his team to the conference finals. Memphis has spacing issues, so until that is addressed it they won't go to the finals.
He was a reserve All-star at the weakest position in the league. Sure, he is top 5 at his position, but there are only 5 or 6 decent Centers in the league. That doesn't make him great, it just makes him rare. You don't hyper inflate his value for that reason. Also, why does his role with the Spanish team matter? Could you name all 5 starters without looking it up? Are you going to give Victor Claver credit for being their starting PF?
Don't take my word for it, do some research, take a poll. Gasol is a top 20 player in the league. Al Jefferson is not
Its an overreaction to a decent season that really wasn't that impressive. If you think that averaging 14/8/4/1.47/1 is a top 20 player, then I just don't know what to tell you. I'm just not going to give that much credit to the 3rd best player on the 5th best team in the league.
