It's fair to say that Hall of Famer Oscar Robertson has not been the biggest fan of the Golden State Warriors.
The defending champions have dominated the league for the last two years and have entertained basketball purists the world over with their attractive style of play.
Despite their success, though, the Big-O has not been impressed. In February, he stated that the only reason MVP Stephen Curry was able to hit shots with relative ease was more down to how he is played by opposing defences than his own ability.

"[Curry] has shot well because of what's going on in basketball today," he said. "In basketball today, it's almost like if you can dunk or make a three-point shot, you're the greatest thing since sliced bread ... there have been some great shooters in the past ... but here again, when I played ... if you shot outside and hit it, the next time I'm going to be up on top of you. I'm going to pressure you with three-quarters, half-court
"I'm going to pressure you with three-quarters, half-court defense. But now they don't do that. These coaches do not understand the game of basketball, as far as I'm concerned."
Robertson - who was the only player to average a triple-double in a season - has now taken a swipe at Curry's teammate Draymond Green.
After a terrific campaign where he finished second in the league in triple-doubles behind Russell Westbrook and earned a first All-Star nod, Green has struggled lately in his team's Western Conference Finals series against the Oklahoma City Thunder.
The power forward was held to just six points combined in games three and four in OKC and was not his usual assertive self on the defensive end either.
In an interview with SiriusXM, Robertson saw his chance to throw some criticism Draymond's way.
"Green's a good player, but he does not have the ability to go over & above what he needs to do to be successful," he said.
"I think (Draymond Green) can do certain things because of what Thompson and Curry have been doing all year long.
"You talk and you talk and you talk, you eventually got to get in there and throw some punches."
The 77-year-old is just the latest in a long line of ex-players who have had negative things to say about the Warriors.
Just recently, Gary Payton said Curry didn't deserve to become the first unanimous MVP.
The Dubs, however, will not pay too much attention to the outside noise as they have bigger problems to deal with.
For the first time under Steve Kerr, they face elimination from the playoffs as they trail the Thunder 3-2.
After a hard-fought 111-120 victory at the Oracle Arena last night, the reigning world champions showed they are not prepared to give up their crown without a fight.
The series shifts back to Oklahoma City for game six on Saturday night.
