Great idea and I have tried to somewhat apply the "lo theory" but with a MR or extra closer so that I can get an added benny of saves. The only problem I see is that you are taking 2 spots for 2 MR's that could be spots for SP's. Those 2 SP's, if average could net you somewhere around 300k's, 25wins, 3.85era, 1.29whip whereas 2 (somewhat unpredictable) MR's will net you 200k's, 17wins, 2.95era, 1.15whip. The loss of those 100 k's and 8 wins will drop in the standings 3-4 points in a roto league (or more). The better era and whip will not boost you more than 2 points. Is it worth the gamble? What am I missing.
