12-team 5x5 roto w/ OBP instead of BA
I'm currently in 1st up 4.5 points on 2nd place. He is actually the guy I traded with here.

He traded me Allen Craig (1b/2b/of), Bryce Harper, and Glenn Perkins for Jon Jay and Aroldis Chapman.

Relevant standings:
5th in HR (very tight in standings)
5th in RBI (within 2 of the guy in 4th but nobody else is close to us)
6th in OBP (very tight)
2nd in Saves (by big margin; probably have 2nd locked up)
2nd in K's
5th in ERA and WHIP

I could easily afford to trade the saves, but there's also a lot of downside risk in K's, ERA, and WHIP. However there's a lot of upside on the offensive side (esp. if Harper comes around) and got a desperately needed MI in Craig. What do you think?

Looks fine, you didn't get enough for Aroldis...
