This guy wants Tulo
I have Scutaro to replace him
my SP are Lester, C. Lewis, Romero, Marcum, Volquez, B. Anderson - start 4
my Catchers were C. Santana (out) and Doumit - start 1

Do I give Tulowitzki, Doumit (we have to have 2 catchers on roster) and Marcum
for Posey (his other catcher is McCann) and D. Price (he has a great pitching staff)
