Bench my whole team today? (FBB)

[dkgojackets]

First round of the playoffs ends today, standard 5x5 H2H yahoo league.

I currently lead

47-30 runs
17-9 HR
46-31 RBI
.360-.323
5-1 W
44-34 K
3.78-6.75 ERA

My opponent has two SP today, and I calculated that even if both go nine innings with no earned runs, his new ERA will be 4.00. Keep in mind ERA is the tiebreaker if it ends in a tie. The only way to tie me in W is for both SP to win and both of his relievers to get a win. His offense will have to match several days worth of production to catch me in the offensive categories, and I can even afford him to somehow win AVG. Plus there's a chance his WHIP drops (he only leads me by .02). Easy decision, no?
