I don't think this is quite as big a deal as you seem to, Jay. I would agree that the Lead shouldn't know if a shot from the top of the key is a 2 or 3. But as C, a lot of times the action is away from you, and there's nobody directly in front of you. In that case, it's easy to see the T's indication, and then I can see echoing it. While I think it's true that the C shouldn't be officiating the 3-point arc (in the T's primary), I don't see anything wrong with echoing the T's signal for a 3point try. JMO
