To me, Nico is the leadoff man this team has needed for 30 years. At least until Armstrong showed up. And you know he can play any position on the field.
Busch is ok but I wouldn't block (or not trade for) anyone because of him. In reality,, though, that's why he's here (cheap, controlled=untouchable). I've begrudgingly made peace with it.
Happ, Suzuki, Belli. 1 or 2 of the 3 can go and it's fine. If they aren't desperately trying to move Happ, there should be an investigation.
