It's pretty easy to get around that stipulation, really -- and to WIS' credit, it still seems somewhat effective as a guard against fatigue strategy.
We might as well tell newcomers they can go find three or maybe four, give or take, of the low-priced scrub players who have the fewest dollars per PA.
One still wonders whether or not the SLB batter fatigue penalties are as severe as they've intended/stated, though.
