The Expos went 81-81> 81-81>85-77 to 71-90 his last year in MON. If that is "okay," you should be thrilled with Bloom's record.
Montreal, also went from 7th lowest payroll to 12th lowest in his 2nd and third year, which indicates he was allowed to spend more than his first year.
With the Marlins, he was allowed to spend a lot.
27th in their first & second years in MLB (1993-5)
17th in his 4th season
7th in the 1997 championship season. He spent big on several FAs.
When the team cut payroll, like the Sox did after 2019, the Marlins went...
54-108
64-98
79-83
76-86
They never reached .500, when he was not allowed to spend.
Okay, he built up the foundation, but nobody wants to hear that about Bloom, now.
He, then joined the Tigers. That team was in rebuild mode, as they were 66-96 (20th highest payroll) the year before he took over. The Tigers went...
55-106 in 2002 (19th in payroll)
43-119 in '03 (25th in payroll- showing it's hard for him to win w/o spending, too)
72-90 (23rd in '04)
71-91 (15th in '05) The spending larger had begun, followed by winning...
95-67 (lost WS) 14th in spending is not mega spending, but he did sign a couple FAs)
88-74 (9th in '07) Spent more than '06 and went backwards.
74-88 (3RD IN SPENDING and a losing record.)
86-77 (5th in spending)
81-81 (6th in 2010)
95-67 (lost 1st rd) 10th in spending
88-74 (lost WS) 5th in Spending gets him to the WS.
93-69 (lost 1st rd) 5th
90-72 (lost 1st rd) 5th
74-87 (4th in spending, and he was canned in AUG of 2015.)
Did his time in DET prove he can win without spending large?
Please, don't take this as dissing DD. I love the job he did with the Sox and have zero regrets. He gave us the best 3 years in a row in my lifetime. I am just not convinced he could have done wonders with the 2020 team and budget. Better than Bloom? Sure/maybe. Better in 2021? Maybe. Better in 2022 and 2023? Probably.
