For general interest -
I haven't quite done an all 1's team yet, but these 2 teams are close. (Both are 2008 card set).
This one was all 1's except at catcher, where Blanco was a 2:

The above team won 85 games, and lost the finals.
The other team in a similar idea was this team:

This team was very cool - won 90 games, but sadly lost the semi's. They stole 242 bases, while only being caught 81 times (Pierre in LF was one of my concessions to mediocre defense). Otherwise, they were all 1's except in LF, RF and C. This team had a really nice duo of Huff (DH) and Adrian Gonzalez, playing at PNC! This was one of the most fun teams I have had!
I sometimes like to set a goal of leading the league defensively in GB doubleplays. When you have a great infield and some starting pitchers who are good at inducing DPs (see the first team, with Hudson pitching!), it can be lots of fun to watch the DPs add up!! I think that this team defense idea works really well in singles ballparks like Fenway (first team) or PNC (2nd team).
