I don't get you people. Wrigley was one of my favorites.
The parks I've gone to: PNC and Camden were best, Wrigley, Citi and Fenway were nice, Nationals, Progressive and Comerica were mehhhhh, and RC and New Yankee are both pretty bad.
Lowry is an upper tier player at least. A lot of +/- stats have him as top 5 I think. Realistically there's no beating GSW but if you surround healthy Lowry with legitimately useful talent then you should be able to be one of the teams that has an actual chance.
