Team pitching staff K's vs. team ERA to date:
White Sox, 53 K's (most in MLB), ERA 3.61.

Phillies, 46 K's, ERA 1.46
Pirates, 45 K's, ERA 4.36
Reds, 44 K's, ERA 4.50

Twins, 42 K's, ERA 2.00

I'm satisfied that moonslav is right to caution against K's. Interesting about the dingers, however. The Sox have given up none.
As for walks, right now I'd have to say that walks are more damaging than dingers and avoiding them is more valuable than getting K's--
Mets, 3 walks (best in MLB), ERA 2.25
Twins, 7 walks (2d best), ERA 2.00
Yankees, 9 walks (3d best), ERA 1.70
Phillies, 11 walks (tied for 4th best), ERA 1.46
Braves, 11 walks (tied for 4th best), ERA 2.81
Padres, 11 walks (tied for 4th best), ERA 2.20.
And here's the five MLB teams pitching staffs with the most BB's given up--
Angels, 21 walks, ERA 5.00
Rockies, 23 walks, ERA 5.75
Diamondbacks, 23 walks, ERA 4.91
Tigers, 24 walks, ERA 6.75
A's, 25 walks, ERA 8.60
