You do make a good point, BUT... Let's look at a thing called run expectancy: https://library.fangraphs.com/misc/re24/ If you look at the table, you'll see the spot with a runner on 2nd with 0 outs. The number is 1.068. This means that more often than not, at least one run scores. So, what's a bigger problem: The offense putting up a goose egg 3/3 times in that scenario, or the bullpen giving up one run 3/3 times in that scenario? I still don't think this is a championship bullpen but saying these 3 losses have been SOLELY the bullpen's fault is inaccurate.
