I think I agree with Sportsman5 that wing
more often means a SF though it can also be a SF that also plays the 2. And that when you get to the NBA the definition drifts more heavily to SF. Example Ray Allen was a wing player at UConn but became strictly a SG in the NBA vs Paul Pierce who plays the 2 and 3 in the NBA and is therefore a NBA wing.
However my point or question was that I thought Austin Rivers is a SG/PG = not wing vs Lamb SG/SF = wing. No one has commented, am I wrong about Rivers?
Maybe I just assumed Austin Rivers was a PG because Doc was a PG. And for that matter maybe I assume the Curry's are SG's because Dell was an NBA SG (although I think Dell played wing at VTech
