Since when do I not like Mahinmi? I was vocal in my support of Pop giving him a chance when he was here. I said it was dumb that the Spurs spent so much time and money on him yet never gave him even one fair opportunity to show what he could do. I pointed out the few times Mahinmi outplayed Splitter the few times they matched up. I did say the Pacers overpaid him in the summer -- and $16M over four years does look excessive for what they're getting.
And "no matter what he does" seems to indicate you think he's doing well. I can't agree with that. A bigman who is shooting 42% with an 11 PER while posting his highest turnover rate and a high foul rate is a below average backup center. It could be different if he were playing awesome defense ... but he's not.
Mahinmi, IMO, was worth around $5M over two years in the open market -- in other words, Aaron Gray type money. $16M was a massive overpayment and simply a case of poor scouting. He's pretty good but he's still raw and there's an upward climb for him to become an average backup center.
To compare, Robin Lopez got less than a third of what Mahinmi got in guaranteed money and is blowing him out of the water -- 56% shooting, 21 PER, less turnovers, less fouls, more blocks, etc.
To be fair to Mahinmi, it's not his fault that the Pacers were dumb. And it was far from the Pacers only dumb move. They also gave Gerald Green $10.5M after he had a few good 10-day contract stints on tanking teams. Swapping out Darren Collison for DJ Augustin has also basically been a bust. Hibbert and Hill are probably both overpaid, etc.
Anyways, tl;dr: I don't dislike Mahinmi. Pacers gave him too much money. He's been pretty bad so far but I think he can be an average backup center one day. Splitter is a much better player so I don't even know how to respond to that non sequitur, tbh.
