In the past offseason, the Washington Capitals had the choice of resigning deadline acquisition Cristobal Huet, or bringing in another goalie as a replacement. The Caps attempted to sign Huet, but were not able to meet his asking price of $5.6 million per season, and had to settle on paying Jose Theodore $9 million over 2 years as a backup plan. So far this has not worked out particularly well for the Capitals as Huet, despite getting off to a slow start in Chicago, has significantly outplayed Theodore.
This has been unsurprising to anyone familiar with recent save percentage history for the two goalies. Theodore has played 2,321 minutes this season and has faced 1,086 shots against. He has stopped 90.1% of shots against, and Hockey Numbers estimates his shot quality neutral save percentage to be .899. Huet is at .918 in raw save percentage and .923 in adjusted. Both these marks are about in line with recent performance - in a post from before this season I used results from the past three seasons to predict both adusted and raw save percentage numbers. The adjusted save percentage predictions were .917 for Huet and .898 for Theodore, both of which are pretty similar to actual results so far.
If Huet faced Theodore's shots this season and put up the same raw save percentage in Washington as he did in Chicago, he would have allowed 89 goals, or 19 fewer than Theodore. If we evaluate the hypothetical using adjusted save percentages, we could expect Huet to allow about 82 goals, or 26 fewer than Theodore has. The effect on Washington would be to improve their goal differential to +55, which would rank them right behind Boston (+63) and San Jose (+59) as the third-best team in the league.
According to some reports, Washington tried hard to sign Huet but he wanted to test the waters of free agency. Still, it is hard to imagine that the Capitals front office doesn't have at least some regret about their decision to go with Theodore - I assume that Ted Leonsis would be quite willing to pay an extra $1.125 million this season (the difference in cap hits between Huet and Theodore) for a 20+ reduction in goals allowed for and as a result a team that, with the division they play in, could possibly have been leading the NHL in points right now.
