I agree with your point but as you like to say follow the math. By keeping some of those you screw yourself 4 yrs down the road...yes keep one of the 1,000-yard rushers, trade the other and replace with a complementary rookie on a rookie salary, etc. Do you keep Bahk and that huge $$ or roll with the guy that won something like 8 straight this yr when everyone went down at 1/4 of the price?
You're correct in that it's not bare-boned but at least next season your depth is paper-thin if you don't do some serious cutting of high-priced vets. The point is it's not a simple formula.... a couple of wrong moves could push this team one way or another.
