You all need to chill about the comparisons. You both forget, they were both rookies. Its not like they have 5 years in the majors behind them. Heck, look how bad Beckham played at 3B this year, you aren't crucifying him!
The bottom line isn't which player is better, its which player fits the team better. I always go back to when the Sox had Albert Belle when I talk about this stuff. Albert Belle probably had one of the single greatest White Sox player seasons ever. However, what a cancer to the team.
The real issue with Nix, I feel, is you already have so many right handed power hitters/semi power hitters on this team. Assuming you get rid of Dye, you still have Konerko, Rios, Beckham, Ramirez, and Quentin. On top of that, if Pods leaves you only have 1, potentially 2 lefties on the team in AJ and Kotsay (assuming Kotsay even plays every day.) Then when AJ leaves, we'll have another RH in Flowers. We have gone through so many years of right handed power hitting teams. They generally don't work. You can like Nix all you want, you can say he is a better fielder (based on only 1 season which he didn't even play everyday) I am not sure you can say he is a better hitter. Getz was incredible for a rookie in situational hitting. But again, the real question is which player fits this Sox team better.
