I know that Gay is a prime target to trade because of his contract, but I see Derozan as being someone who we can probably get more value for...
The reason is that Derozan will be traded based on being a 2 guard with potential who is averaging close to 20 ppg. His contract is not great, but it's not bad either when you compare it to the rest of the 2 guards in the league.
At the end of the day, Gay is MUCH BETTER and has already proven that he can be useful on a playoff team. Derozan would be no more than a role player on any other team
What I'm saying is...trade them both...but if I had to pick, I would choose Gay in a heartbeat
