It is pretty ovbious that you prefer SLG to OBP. I however prefer OBP to SLG. Mostly because most sources seem to think that 1 point of OBP is equal to 1.2-1.7 points of SLG. Not making outs is important. If stats are close, I will always go with the higher OBP. I actually think there is a good chance that Durham finishes the year with better stats than Weeks, but Weeks plays better than Durham from here on out, which is what I think is more important.
