I think this is the key here for the Pistons. He easily becomes one of our best shooters on the bench and is an adequate defender against PG's (Chauncy obviously would have to guard opposing SG's). In the playoffs if teams start clogging the driving lanes Dixon can create a little more space to work with.
I've watched a LOT of Raps games and Juan isn't a chucker. He won't throw it up every time he touches the ball but if he's left open he's not afraid to take a shot.
He never really had much of a home in Toronto and spent most of this season playing out of position as a PG. He was kinda OK at it but you'd have to be in a REALLY bad pinch to put him there.
