Yeah probably not, he would have been a restricted free agent after the Phoenix series, I guess he could have received a Rudy Gay size contract offer as people thought he was going to make a full recovery from that minor knee surgery, but in actuality it was the final straw that broke the camels back.
I do wonder if he had been coming up on restricted free agency would he have rushed back to get on the court 10 days after surgery? Would a longer recovery time have benefitted his knees?
I suppose Roy's knees would likely have ended up where they are now regardless of his contract situation. If Roy was a restricted free agent last offseason, and only took the 1 year and was now an unrestricted free agent, he wouldn't get more then the MLE.
It's pretty easy to criticize the extension in hindsight. I guess KP's point was the team would've had to pay a max 6 year contract at the end of the season so it was better to just do a 5 year extension at the time.
