I remember people thinking the wild card was going to ruin baseball.

Turns out it was probably Bud's greatest idea.

I think that if the DH is adopted in the NL, people will grumble for about a year and then get used to it. Maybe even eventually prefer it.
For example, when Votto was playing on a sore knee last year, it sure would've been nice to have the luxury to DH him while the medical staff took a few weeks to decide if he was really injured or not.
