graymatter, you're ahead of the game. It took me some research and actually drafting the rest of my team on a tentative basis (figuring I could adjust it as I need later), so I too have a could idea not just who I can add for my 5th pitcher (only needed l replacement) + his 4 teammates. But it takes some figuring to wind up within the salary cap.
By my figuring there is the l perfect (master...) owner, then
5 who need 1 more pitcher
6 who need 2 more pitchers
6 who need 3 more pitchers
6 who need 4 more pitchers
My suggestion is that if you need 3 or more new pitchers, you'll have to think outside the "bun" or select pitchers you might not ordinarily think of using on a team in order to not keep picking what others will also select.... Anyway, its an idea.
