Even with the signings, we really could only win 70 games or so, tops IMO. Go up and down their squad, and the only spots where they are average or above the league average for production are C (I-Rod), 2B (Vina), SS (Guillen), and OF (Young). Higgy is weak, White only gets 100 games a year.
The staff has promise, but is still a few years away, and the bullpen is a mess. If things really go their way 75 wins is attainable, but let's not get carried away.
Side note: Damian Moss was a FA??? After 2 years??? I would have tried to gobble him up in a second. He has good stuff, is a lefty, but lacks control...sounds a bit like Randy Johnson...although the two aren't really comparable, just the above statements.
