Quin won 2 series he wasn't favoured for. Great.
Quin lost again dynasty GSW minus his starting PG who was having career year. Ok.
A loss against dramatically bad matchup and easily favoured Houston team. Ok.
A loss against the same Hou team but
Quin prepared a scheme that made possible for Jazz to win but the players couldn't hit wide open shots. Good.
3-1 loss against Denver who had the MVP and their perimeter defender came back while Jazz didn't have their second offensive option. Kinda bad.
It doesn't average out to mediocre even if you just think result based. Quin makes subtle adjustments every series and most of the time is step ahead of his opposition even if he doesn't always have the necessary players.
But then who is a good playoff coach for you recently and who is great?
A good playoff coach? Someone like Jerry Sloan or Rick Adelman or even Mike D'Antoni - guys who haven't won it all but have consistently fielded some very strong playoff teams that got beyond the second round on multiple occasions (as well as made the NBA Finals). Sloan coached the Jazz to six Western Conference Finals and two NBA Finals. Adelman coached the Blazers/Kings to four Western Conference Finals and made the NBA Finals twice with Portland. Mike D'Antoni, who hasn't made a NBA Finals, still managed to coach Phoenix and Houston to the Western Conference Finals three times in his career.
Now those are just what I would call good playoff coaches - not great. Great, obviously, is for someone like Phil Jackson or Gregg Popovich or Pat Riley. A very select group of coaches who've won multiple NBA titles over their career - and with Jackson and Riley doing so with two different franchises.
I already listed out who I felt was a mediocre playoff coach - someone like Dwane Casey, though even he has a trip to the Eastern Conference Finals. Still, on the whole, I think his playoff resume is very similar to that of Snyder ... or at least, his time with the Raptors.
But I'm not going to fall over myself praising Snyder for winning the 4/5 match-up when, historically, it's the one match-up where the lower seed legit wins a lot of the time. Since 2010, here's every 5 over 4 'upset' in the playoffs:
2010: Utah (5) over Denver (4)
2011: Atlanta (5) over Orlando (4)
2012: Clippers (5) over Memphis (4)
2013: Chicago (5) over Brooklyn (4), Memphis (5) over Clippers (4)
2014: Washington (5) over Chicago (4), Portland (5) over Houston (4)
2015: Washington (5) over Toronto (4), Memphis (5) over Portland (4)
2016: Portland (5) over the Clippers (4)
2017: Utah (5) over the Clippers (4)
2018: Utah (5) over Oklahoma City (4)
2019: None
2020: Miami (5) over Indiana (4)
2021: Dallas (5) tied with Clippers (4), Atlanta (5) lead 3-1 over Kew York (4)
So, 11 of 12 seasons a five seed upset a 4 seed in the playoffs. Some these were due to the five seed actually having home court - but a lot of the time, the upset happened without the team having home court. Total, 13 series saw the five-seed advanced to the second round. That is out of 22 series total. That means, since 2010, the five-seed actually wins the series nearly 60% of the time compared to the four-seed. That isn't counting this year's playoffs, where the five-seed is either tied with the four-seed or up on the four-seed.
My point? If your high mark in the playoffs as a coach is winning a first-round series that has historically been won by your seed anyway, I'm not going to give you a great deal of brownie points for it. They were good wins. But they were also wins that happened three and four years ago. They're wins that ended in completely non-competitive (for the most part) semifinal series. They're wins that, a season or two later, were followed up with a bad first-round loss and a 3-1 blown lead.
All that pretty much paints a picture of a mediocre playoff resume. It's not bad, which I think you somehow think I'm saying. But no, I'm not going to suggest Quin's playoff resume is good.
But I as I've said a few times already, my view will clearly change this playoff. If the Jazz go out and make the WCF, I will readily concede his resume has improved and we should bump him up to good. But a good playoff resume has to be more than just a couple first-round wins and then a few non-competitive series. Maybe if the Jazz had put up more of a fight against the Rockets either year they lost to them, or they didn't blow that 3-1 series lead while leading by 15 points midway through the third quarter in a closeout game for them, I would be inclined to give him a 'good' mark there. But they didn't. So, why would i? It just seems so unearned. To me, being good at something means you're consistently achieving a level of success that puts you on a different level than most your peers. Well, if we consider Quin's playoff resume good, what would we consider mediocre? Nate McMillan? Frankly, I consider his playoff resume pretty bad - this year not withstanding. Why? Because the dude has made the playoffs nine times and only advanced beyond the first round once. In that context, using McMillan as a template, ranking Quin as mediocre makes sense.
Really, tho, this is an ever evolving situation. Only a select few coaches can attain, and sustain, greatness. Everything else is a shuffle. Pop is not likely to ever lose that greatness status. But someone like Rick Carlisle? A decade ago, I would have put him as a great playoff coach. After all, he had just won a NBA title with the Mavs and had consistent success at Detroit and Indiana before that, taking both teams to the Conference Finals once each. He went from 'good' playoff coach with the Pistons and Pacers to 'great' playoff coach with the Mavs after the 2011 season and their title.
But now? No. I wouldn't consider him a great playoff coach. Since that 2011 season, the Mavs have failed to make it past the first-round once (and likely won't again this year). Still, I cannot justify putting Quin Snyder among Carlisle, a guy who's coached three conference finals, one NBA Finals and owns a championship. Not yet, anyway. And I think that's reasonable. Brad Stevens is another coach I'd consider a good playoff coach, but again, he's got three appearances to the Eastern Conference Finals. How can I reason putting Snyder among a coach like that, a guy who's failed to get beyond the semifinals yet - and is 1-8 in semifinal games total?
I can't. I won't. Not yet, anyway. But a run this postseason can absolutely change that. It's that simple.
