that's not as funny as you might think...
1b: Ike davis
Ike is a safe bet for 30 hrs and GG caliber defense. His average will get better and I can definitely see a typical season for him being about .270 with 40 hrs and 120 rbis
2b: Murphy
Easily one of the most UNDERRATED players in baseball. He has great plate discipline who doesn't strike out much. He will hit for a good average around .300 and contribute 40+ doubles to the lineup. He will get better with his defense and if he can just be average defensively, he will be a very good player.
SS: Tejada
GG caliber defense. Can hit for a good average and expect it to be .290+. He too has great plate discipline and can work the count. He doesn't have much power obviously but can be a solid doubles hitter with at least 30-35 per year.
3b: Wright
We know what we have here.
C: D'Arnaud
All he needs to do is hit for a decent average with 20+ hr power and good defense.
It certainly has the potential to be a great infield.
