Obviously the top guys are:
Improving Guys who we don't have a shot at:
But these guys..no thank you:
Afflalo (can't create his own shot)
Mayo (If you think Ellis is inconcsistent watch Mayo)
Matthews (see OJ Mayo inconsistency)
Allen (old, slow, one trick pony who can't play D)
Tyreke Evans can't shoot lol if he improves his shooting hell yes but if he doesn't hell no. The guy has played 3 different positions and if he doesn't develop a jump shot his worst position is the 2 spot.
Derozan is one of the most overrated players in the league especially on his contract. He is the Deandre Jordan of shootin guards right now. All potential, will he reach it? I don't think he ever will.
Iggy would be awesome but we missed that boat when he got traded to Denver and he is a tweener at the 2 and 3.
Jeremy Lamb could me great, but their is a reason he was still there at 12. I think at best Lamb is a Kevin Martin type shooter but doesn't benefit from the free throw attempts Martin does. I just never saw him really try to attack the rim. It's all moot though because the Thunder wouldn't trade him, he is on his rookie contract which keeps them from being way over the cap.
Of the players you listed who are available I wouldn't take a single one over Ellis.
