I was there.. I didn't love the tryout format..20 minute Full field games doesn't seem like the best way to either showcase or identify individual talent. That said, I'm sure the selected team will do well, most players I saw there could play, a few real standouts and the rest separated by the obvious like great speed, a good draw taker, a couple of great saves. a "known player" etc..
As far as 2022.. I'll wager 4 or 5 will make it.
The roster should be out around the weekend so we will all find out together..
