Umm go check defensive war on tim anderson the 1rst two seasons. and tell me he is below average when he grades positive in the first two seasons overall. and once again he grades positive in 2018 there is no surprise here he is above average at worst and + at best. I never said guys can't improve you just not gonna see -1 war defensive players turn positive. when you a -1+ war defensive player that means you are a brutal defensive player.
