I'd seriously rather play Pressey than watch Nelson consistently jack up contested shots.
Main reason Nelson takes so many contested shots is nobody else on this team can get him an open shot.
Took good shots in Dallas when he had Monta, Dirk and Parsons working to get him the ball with time in open spaces. This Jameer Nelson is like the Orlando Jameer of previous 2-3 years since Dwight Howard left.
Nelson takes these shots because he is often the best creator off the dribble against defender & set defense on the team. If it wasn't him, it would be someone else taking that contested shot. Often an even worse ball-handler & shooter trying to force up a bad shot (like Bradley).
It is the team more so than Jameer Nelson. This is what role players look like when they have no stars to play off of.
