Having just turned 19, Brennan has sprouted to 6-4 and 190 pounds. The extra notches on the height chart since he arrived in Prince George before the pandemic have helped him cover more net. Possessing the classic goalie frame, just as important as his pro-level athletic ability and quickness, he doesn't panic and is good positionally. He's known for gobbling up hard shots without rebounds and has a good, active stick to knock away loose pucks in his crease and to distribute the disc when he leaves it.
