The Cubs not only need to move on from Jed, but they need to upgrade and improve their entire front office, scouting departments, player development, etc. Our manager and coaching staff isn't getting the job done either IMO.
It seems like every time we trade for or sign an established and good MLB player, they get worse as soon as they get here. We're either bad at evaluating MLB players or bad at coaching them, though it's likely both.
Go hire everyone away from the Brewers, since they are better than us year in and year out and with a fraction of the payroll.
