True, but some of those slots go to returning 60 Day IL players and another 5-7 for Rule 5 additions.
If we do as I suggest, and add just 3-4 quality FAs or trade additions, instead of 7-10 "quantity additions" like we have in the past few years, we won't need to trade Walter to open a slot, but if we sign a bunch or mediocre FAs, then he may get squeezed.
