I'm not a fan of punting in roto. As another poster elaborated upon, the 1 point in the saves category is extremely difficult to overcome. In H2H, I have no problem punting, but saves is another tough one to punt since you will also take a small beating in ERA and WHIP. You would have to be prepared to stream pitchers on a daily basis if one of your SP has a bad outing to overcome the ERA and WHIP hit.
However, all is not lost:
The reason one punts a category is to take the most value in the earlier rounds. If you punt SB, Mike Trout is no longer a top ten option.
So the reason you punt saves is to reduce the number of high draft picks "wasted" on closers. Why not wait until the end of the draft? Your last 3 picks and take middle relievers with a clearer shot at making the closer role?
Kyuji Fujikawa (behind Marmol)
Vinnie Pestano (behind Perez)
Kenley Jansen (behind League)
Luke Gregerson (behind Street)
I have employed this strategy, along with being aggressive in free agency, in one of my leagues and consistently rank in the top 4-6 range. I still get the positive effect in the draft and not the 1 in the category.
