I've seen a lot of goalie talk on the board lately. A few teams keep track of shots so you can get save percentage numbers. Here are numbers from some players you have all mentioned and some that I found interesting:
Jason Schaubel (Barrie Jr. Colts) - .934 (14/27 games had shots tracked)
Matthias D'Souza (Ottawa Myers Automotive) - .918 (10/17 games had shots tracked)
Colin Ellsworth (York-Simcoe Express) - .917 (13/20 games had shots tracked)
Kale Osipenko (Ottawa Valley Titans) - .917 (13/22 games had shots tracked), worth noting his tandem partner has an .880 SV%
Mateo Beites (Barrie Jr. Colts) - .913 (8/17 games had shots tracked)
Jack Ferguson (Ottawa Myers Automotive) - .907 (11/21 games had shots tracked)
Riley Barkey (York-Simcoe Express) - .882 (13/23 games had shots tracked)
These are combined stats from the regular season and playoffs of these leagues. No tournament games were included. Unfortunately the Alliance, GTHL, NOHA, and OMHA West either don't track shots or do it very rarely. All the information comes from the GameSheet website. Here is a link to it:
