I also don't buy the fact that Asik is a total 0 on offense. A total 0 on offense is someone like Joel Przybilla.
In 2012-2013 when Asik started and played 30mpg for Hosuton, he averaged 10ppg on 54% shooting. That's 1 less ppg than Robin's 11 last season.
So that's also another argument that needs to go away.
I'm not going to quote both, but I saw that you asked to have an objective view. I think most do. We look at Lopez with a more holistic approach, as with Asik. Lopez was the better offensive rebounder last year. Asik had one game of 9 Offensive Rebounds(in 2012-2013... using what you measured him with... that's where all of Asik' stats will come from). Lopez had 4.
Defensive rebounds Asik tore up that year in Houston.
One thing I do notice, which might have helped skew some, was that Asik really didn't have great scoring games against Portland in 2012-2013. In those games (Series split 2-2) Asik had 16/9/9/4 in those games. The rebounds are up there, but that's to be expected. With Lopez against Houston (Regular season) last year, He had 0/13/16/11. (I did the math, Lopez in fact scored more points. lol, irrelevant, but I wanted to see).
I also just did a quick stats look. Asik: Only has 1 year of being a starter. Lopez: Has 3 (Countin the one in Phoenix... I believe he started there..) Experience will trump most everything. And in 2 of those years, Lopez had an 11 ppg (8.0 PPG career). Also, Lopez in his 2nd straight year of starting went from 5.6 RPG to 8.5 with us. What's not to say that doesn't rise?
This argument will go on forever, but there's reason to think Lopez is a better fit to this team than Asik. Really, stats don't prove Lopez' entire worth. Whereas, Asik has been known to sulk at times.
Lets put it this way. Say we did have Asik last year, and the same thing happens with Howard where he manhandles Asik. (And he most likely would, Howard can do that to damn near anyone). Asik has had a propensity to sulk and whine and complain. Now Howard has gotten into his head and we would be toast. Lopez, however, knew what was happening but just took the punishment as a part to help the team. He could never STOP him, but he could create enough conflict to give us chances to win.
I'm using hypotheticals because, really, that's all we have in these arguments.
Stats have never measured heart and fortitude in athletes. But those are the two biggest factors in basketball, IMO. Asik has his skillset, but he has some troubled areas, just like Lopez. I would still, after all this, take Lopez all day every day. That's not being a homer, that's just what I have seen, both with stats proving what they prove and my own eyes seeing what they see.
