He's had just over a month to fix that problem. We have no idea what he's trying to get done right now. Trades have to work for all teams involved, not just ours (unfortunately).
but he HAS made moves to try and fix the problem. none of them were GOOD or even DECENT moves.
it's not all about trades.
we have 4 relievers sitting in AAA with ERAs under 4. Rizzo refuses to call any of them up for some reason.
