BJ was amazing. Then got injured, and it was over for him.
Rauch, Francisco and Santos were all bargain bin attempts at closers because our thinking was that spending money on a proper closer wasn't worth it...
Bargain bin?
Santos was coming off a 30-save season with ridiculous strikeout numbers. He was basically exactly the kind of pitcher that people think of when they think "closer" a big, strong, hard-throwing righty with a power fastball and a wipeout secondary pitch (in his case, a big slider)
Francisco was acquired for Mike Napoli, who was a big piece in the return the Jays got for dumping Vernon Wells' albatross contract on the Angels. Most people harangue Jays' management for that trade, calling giving up a very solid player in Napoli for Francisco, who had a 25 save season with the Rangers and was considered a very good reliever who had closed in the past when he was acquired.
Rauch had 40 saves before the Jays gave him over $7m for 2 years
Francisco Cordero was even signed for $4.5m for a year to be the setup and backup to Santos and had hundreds of saves in his career with the Reds to date.
So that's 4 guys with closer experience, at least a season of good performance in the role (and in some cases more) and most of them (basically everyone but Rauch) being big flame-throwing strikeout guys too. And look where it got them.
None of that wasn't "bargain bin". That was doing what everyone clambers for teams without a "proven closer" to do: spend on big, enticing arms who have shown they can pitch in the 9th.
also, the salaries they got from the Jays:
Francisco: $4m
Rauch: $2.5m/$2.75m
Santos: $1m/$2.75m/$3.75m
Cordero: $4.5m
So the team spent $21m over 3 years plus trade assets (mostly Napoli, considering Nestor Molina was a shrewd sell-high move) on guys that fit the mould of "proven closers" and got sweet ****-all from it while little unheralded, soft-throwing junk-baller Janssen took the role and ran with it.
