Javonte Green might be a guy who is ok with getting sporadic playing time, can help out on the wing, is Tatum's buddy, can defend the perimeter, showed an improved outside shot in Chicago. 
Good defender who doesn't require a lot of touches on offense (like someone like Oubre, for example)..
And rumor has it, he is open to returning to Boston. 
Question to me is, how is he moving these days? Missed most of last season with injuries, had knee surgery in January - which is a little scary for a guy who relies a lot on his athleticism/explosiveness. 
I say at least bring him in for a workout and if he looks good, give him the veteran's minimum. He's still only 29 so should still be in his prime. I'd be more worried about a guy coming off knee surgery if he was older than that..
Sidenote: I'm kind of surprised Ainge hasn't signed his guy "Romey" yet haha. Guessing that perhaps Utah just doesn't have a roster spot to give him, with all the other moves they made and dudes they drafted. Or, Romeo is just bad, so nobody wants him 

Sidenote: now that I think about it, Wiggins is 24. He's a little bit older. He's kind of in a similar spot to Pritchard in terms of age, NBA experience, contract situation. I bet OKC is working with Wiggins on finding him a team where he'd be able to get more minutes. Like I said, Denver, Memphis, Chicago and Charlotte were some that popped into mind - where he'd probably get more playing time than he would here..
