Using the performance of the team to rate the impact of the player is just not a statistically sound method. There are so many external factors that could explain variation in the team’s performance that it makes any conclusion flawed. What was the QOC of the teams they were playing, who else was injured on the team, how many B2B games were there, how many home games were there? You can go on and on, there’s way too much noise in that kind of analysis.
Measuring the actual performance of the player on the ice, the Goli-Spurgeon pairing performed better than the Brodin-Dumba pairing. What influences this? Offensive zone start time. All stats are flawed, but I think it’s pretty easy to come to a conclusion that Spurgeon’s performance is a lot more impressive with Goli than Dumba’s is with Brodin.
Dumba has not been the same defenseman since his injury. He’s nowhere near the defensive player that Spurgeon is and he doesn’t have the shot anymore to justify any offensive upside either. He’s a right-handed Scandella being propped up by his best friend.
Dumba missed games against:
AZ, BUF, CHI, CGY x 3, DAL, DET, EDM x 2, FLA, LA, MTL, NSH, OTT, PHI, SEA, SJS x 2, STL x 2, TOR, VAN, WIN x 2. So 12 Playoff teams and 13 non Playoff teams games missed. 14-9-2 was the record.
Spurgeon missed games against:
ANA, AZ x 2, BOS, CGY, CHI, COL, DAL, EDM, NJD x 2, STL, TB x 2, TOR, WIN, WSH.
So 10 Playoff teams and 7 non-Playoff teams games missed. 12-3-2 was the record.
Looks, to me, like they had the better competition when Spurgeon was out of the lineup.
Without Dumba MN gave up 4+ goals in 13 games (over half of the games he missed), and gave up 2 or less goals 6 games.
Without Spurgeon they gave up 4+ goals in 4 games, and 2 or less goals 9 games (over half of the games he missed).
Dumba and Brodin weren't out at the same time last year. Brodin and Spurgeon were. There were a few games where Brodin, Spurgeon, and one of Goli/Merrill were all out.
There was 2 games (WSH and ANA) when the d-corps consisted of Dumba, Kulikov, Merrill, Benn, Addison and Mermis. Somehow they won both of them.
FWIW MN was 48-19-6 (114.6p pace) with Brodin (missed 9 games).
