The only season in which Jones may have had more opportunities was last season thanks to Durant's injury, but then (as mentioned before) Jones also got injured - and missed about half the season.
Jones hurt his knee and missed 12 games early in the season. He didn't miss about half the season or even close to it: he just fell out of the rotation - while largely healthy on a ludicrously-injured team - because he sucked outside of a hot stretch to start the year.
You could be right - if so fair enough. I admit I looked at the consecutive DNP's and assumed they were due to injury, since it seems odd that he got plenty of minutes (and did pretty well in them) prior to the injury, then suddenly saw very limited minutes after the injury. If that was an incorrect assumption, then I take that back.
But still, you do you realise that Crowder only averaged 10 MPG in Dallas, right? That's actually less than the 14.7 MPG that Jones averaged in OKC. Probably not the best example for people to use when trying to suggest that minutes played represents the coach's faith in the player (and hence, the player's ability).
Again I'm not by any means suggesting Jones is going to break out as some kind of beast player - just saying that every player deserves a chance, and a change of scenery can do a lot for a guy.
My guy feeling tells me that he probably will be a bust, but I feel like he's got a better chance than somebody like James Young, who was thoroughly outclassed by Summer League. I know people will argue "but Young is only 20!!!", but whatever. I've watched the guy play, and he looks as lost as Fab Melo - but at least Fab was 7 feet tall and could block shots. Yong can't seem to contribute anything of worth unless it's in the D-League (which, worth noting, Fab Melo also dominated).
