Prince has really not been a very good player for many years now. He makes $7.7M and so fortunately it'd be difficult to make the salaries match anyway. I'm sure Memphis would make him available though, so it makes sense that someone leaked his name.
If you are looking at Memphis, I wonder whether they'd trade Quincy Pondexter, and I wonder whether he has recovered from his stress fracture from last year? He hasn't been very good this year and has sort of been lost in the shuffle there. He's got 3 more years on his contract AFTER this year (at ~$3M/yr).
