Funny, I heard nearly the exact opposite although admittedly second / third hand. My friend said the Sharks will be the best AA team up north. The reason the 03s left was because they might not have made the 16AA team as it was heavy 02. Neither GSE or SC looked strong on paper. Best players at GSE, SC went AAA at both 15 and 16 levels.
In general, 16AA is a tough level talent wise (as opposed to 12AA and 14AA). By now kids are starting to decide if hockey is really worth it to them anymore in California. I think many decide it is AAA, prep school or bust. Otherwise it makes more sense to drop back to A/B or HS and enjoy playing with friends. That leaves 16AA light in level of play.
In any case....that’s why they play the games. Looking forward to the season.
