It's very close between Bergman and Dechaine.
Just for fun, I threw their tournament records from the past 3 years into a spreadsheet.
I weeded out all events that weren't 9b and 10b (including American Rotation)
I threw out mosconi cup for both of them since that's free money even if you lose.
If I wanted to be really thorough I'd see if any of the other events
are free rolls or invitation only, but I was lazy.
I also don't know if maybe AZ missed some events, or had typos, or
has some data that still hasn't been entered.
The results look like this:
Total money won:
------------------------
Bergman: $145,563
Dechaine: $90,733
However, it's worth pointing out that $40,000 of Bergman's money came from a single gambling set with Oscar Dominguez, where Bergman won $40,000. It's unknown if there are other similar sets for either player, that didn't get labelled "tournaments" and wouldn't show on the AZB money lists.
Another $10,000 came from a single event with just 4 players, "young guns vs. old school", with justin and sky vs. archer and morris. This is a one-off, independent, invitational event that MD couldn't have entered, and part of it involved 8-ball, so you could argue that shouldn't be in the money list either. Between that and the 40k set with oscar, you could argue that bergman actually made a little less than dechaine in tournament prize money.
Top 3 Finishes
--------------------
Dechaine: 1st x 16, 2nd x 7, 3rd x 3 out of 57 events.
Bergman: 1st x 12, 2nd x 4, 3rd x 0 out of 39 events.
So bergman has fewer top finishes, but also fewer attempts. And this doesn't differentiate
between a $1000 first place and a $10000 first place. At a glance though, Justin
has a few 5-figure wins and mike doesn't have any in the past 3 years (not counting the
$10,000 prize for losing the MC). Mike's biggest payouts are a pair of $7500 payouts,
while bergman 2 wins in the Smokin' Aces barbox event worth 20k and 15.5k.
Average winnings per event
---------------------------------
Dechaine: $1691.81
Bergman: $3732.38
So this is just the amount of money won, divided by number of events entered.
Bergman's is way higher obviously. If you remove the skewing caused by
his set with Oscar and the Young Guns event, it's $2450.33. Still significantly higher.
So it looks like he wins more money, more consistently, though MD makes up for it
by entering more tournaments.
Performance in events they both entered
----------------------------------------------
Don Coates Memorial 9b - tied 5th
Tornado Open 2016 - JB 5th, MD 9th
US Open 9-Ball 2016 - MD 13th, JB 17th
DCC 2016 9B Div. - tied 70th
Turning Stone XXIV - MD 2nd, JB 17th
SBE 2015 Players C'ship - MD 4th, JB 17th
US Open 9-Ball 2015 - JB 9th, MD 13th
US Open 9-Ball 2014 - MD 4th, JB 17th
DCC 2014 9B Div. - MD 6th, JB 13th
3rd Annual Steinway Cl. - MD 7th, JB 9th
So Mike comes out ahead here, Bergman's only finished above him twice out of 10 events
that they both attended. MD's final 4 in the US Open is pretty impressive.
Overall, I'd say Bergman is our new "discount shane". Especially because the trend seems to be that Bergman is on his way up while Dechaine is just holding steady or maybe slumping a bit. If we want to look at MC performance, Justin's done better too, though nobody's doing really well on team USA. In the most recent event, Justin won 2 matches and Mike didn't win any, and that brings their individual match records to
Dechaine: 5 - 16 (23.8%)
Bergman: 6 - 10 (37.5%)
For a while, Mike was clearly the next in line after SVB, and over the long haul he's been very consistent, earning 30-60 every year since 2008. He's grinding it out and seems to be a true professional in the sense that he's making a living year after year on his pool earnings. Bergman meanwhile is very streaky... he'll have a miracle year (2008, won a ring game for 20k and a tar match for another 20k) and then years where he barely makes a thousand bucks in tournament prize money. But generally speaking, he wins more money in fewer events, and especially in the last 3 years.
