I don't know that the pay difference is worth noting too much in this context. Bottom line is they improved their back-up 5 and didn't break the bank to do it. A back up who can still get better, albeit in steps and not leaps (and his fouls have been down, relatively, and his blocks up). It's not like they did what the Warriors did last year and paid Kwame 8 million to come off the bench. He's not Robin Lopez, but he is who the Pacers got. He's not the steal of the offseason, but he's not a total stiff like Petro was when got 3/10 from the Nets or Colangelo giving Gray 2/5. Or giving Jackie Butler 2.5 a year.
To me, legit might as well mean average. Players who aren't average might fall out of the league when their contract is up; they're not legit. A whole mess of people on this board (not talking about you) would have sworn up and down that Ian wasn't legit, that he was just a scrub on his way out of the league. But no, he's an NBA player.
