Maybe you should do what you're paid to do (make open shots) before you open your mouth

With the exception of Green and Pierce (who are our two best scorers right now) Terry has essenially been our next most consistent outside shooter.
Yes I know Terrence Williams has shot better, but he's played very few minute and put up few shots so it's too small a sample size to compare.
Terry has shot fairly well for his position (even 43% FG is passable for a 6'2" SG) and he's given us double figure scoring off the bench which is something we have sorely needed in the past. IMHO he's played some pretty solid defense and has hit some pretty big shots for us.
In Terry's case it's not so much that he's not played well, it's just that his offense has been inconsistent. He's had some great games and some mediocre ones, but he's been a valuable member to the team regardless and has made some game winning plays on both ends of the floor.
Regardless Jet is another PP/KG type. He's the type of player who tends to elevate his game to another level in the playoffs, and I expect no less this season. It's a shame we weren't able to keep Ray as well as signing Terry (as DA intended) because a backcourt of Jet + Ray would have been devestating and much more dangerous than Jet + Lee, but alas it is what it is.
