I think Waleskowski had the most impact on a game as a player. I think that
Chris Wright has already had a bigger impact on the program by attracting a higher level of teammate (and locals) just by his presence. It was his commitment to UD that was the turning point where other recruits (mainly locals) really started to believe that we had something very good forming at UD. He also is attracting national publicity and notoriety throughout his whole career so far. For the last few years, when pundits/fans/etc think of UD basketball, Chris Wright is the first thing that comes to mind. He is the face of the program behind BG.
I called him a potential program changer when he commited to us, and I think he is transforming us more than any other player this decade. He made it cool to buy into the system and work hard over the off-season. Lots of players had a hand in changing the culture, but his impact is the largest, IMO.
That is the logic that I use to vote for Chris Wright as the "UD Player of the Decade". It's his long term impact on the program that I value the most.
