Not sure Hoffman has enough starts to compare him to Anderson. looking at the stats 3 Starts, against San Diego, 29th out 30 teams in team hitting, Philly is 26th. LA, ranked 6th in team hitting is the only true test and he gave up hits, yanked in the 5th, not so great. If he looks the same against the cubs, they are starting to hit,  I don't see how you keep him.  He needs a quality start against the cubs a team that can hit. If he gives up hits/runs send him back down.
