Dolis blew like 3 games to Boston in the span of 10 days, and Chatwood blew several games in the same week at a different point.
There was a span against Seattle and Washington where we lost a handful of close games and Romano was barely used.
Charlie definitely cost us at least 3-4 wins and you can’t convince me otherwise.
EDIT: I also recall that 4 game sweep at home vs Tampa. That was a brutal stretch of bullpen management
