Yep, there's a lot of different approaches. For amateurs, it makes sense to settle on an approach and become consistent at it. Pros sometimes change their hitting approach game to game or series to series depending on the pitcher, etc. It's too much to expect a college kid to do that with ease. Most coaches want the lead off hitter to take some pitches and take the pitcher deep into the count so the team can see what he's throwing. Seth could have used a bit more of that, IMO, but he had a whopping OBP anyway, so he stuck with what he knew.
