(That would be super goofy, I don't know if it would work but it would be interesting). He could be a swiss army knife off the bench for the Cavs, running the bench offense and also slotting in at SF in their small lineups featuring Kevin Love at center, they could even potentially try and play huge with Gay essentially playing the 2. But they are a team that could actually use Gay as just an expiring. I don't know exactly what sort of ammo they would have in the tank to make this work, and the Cavs also already have 2 very good forwards of course. I think it would be hilarious and awesome. I think they should just go all in on the 90s ball and roll with it while talking about how playing Rudy Gay at PF is basically their version of the Warriors death lineup. They could just play Gay at PF and have a starting lineup of 4 guys who are iso scorers and questionable shooters. Here are the latest NBA trade rumors for the 2016-17 NBA Season.
His fit is a bit questionable since both Knight and Bledsoe are good iso scorers as well, but he would almost certainly be a sizable upgrade on the other small forwards on the roster, so as long as they did not give up too much for him it could be a nice fit. Some trade rumors are geared towards targeting a particular teams area of weakness and how a trade with another team can improve that liability, and hopefully make it a win-win situation for both parties involved.
