Veron has never really proven to suit any role, for any team in the last five years.
I know this is an oversimplification, but here are some numbers to put Veron's time here in perspective (stats are for the regular season for the players time at Red Bull):
Veron: 1729 minutes played, 10 goals, .52 goals/90 minutes played
Sam: 7145 minutes played, 20 goals, .25 goals/90 minutes played
Grella: 5136 minutes played, 16 goals, .28 goals/90 minutes played
Muyl: 6279 minutes played, 11 goals, .16 goals scored/90 minutes played
Royer: 7246 minutes played, 36 goals, .45 goals scored/90 minutes played
Sam, Grella, Muyl, and Royer were the wingers that all got minutes ahead of Veron during his tenure here. Veron's goal/90 ratio for Red Bull is better than all of them, with Royer being the only one that's close. Obviously, the comparison isn't perfect because Veron didn't play on the wing a lot, but when you factor in a lot of his starts came either in the ineffective 4-2-2-2 or with the B Team, I thought it was interesting.
Not saying Veron should have started over any of these guys, as there are other facets of the game like defense that are important, but he scored a goal every other 90 minutes, that's not that bad.
