7. Shaquille O'Neal - 20.7
Perhaps it shouldn't surprise you that "The Big Shaqtus" himself Shaquille O'Neal bulldozes his way onto this list. He only played 108 times for the organization, with a paltry five of those appearances coming in the postseason. It is clear O'Neal was past his best when he joined the Suns, yet he still managed 16.5 points and nine rebounds in 29.7 minutes of action.
O'Neal also came at an important time for the team, and he was an All-Star at age 36 when the midseason exhibition came to the desert back in 2009. The fit wasn't too bad either - which may explain the PER rating he managed to produce during his time there - as he had Steve Nash and Amar'e Stoudemire for company.
In a fun link to the league as we know it today, O'Neal was also teammates with Goran Dragic and Robin Lopez as well. From 1997-2002, O'Neal led the league in PER every year. Every. Single. Year. Such was his dominance on the court that even when way past his prime, he had a tangible impact for the Suns.
