Pretty simple. You can't win if you don't shoot.
If Cassar is aggressive and shoots he wins. If he parades around tyeing up for the first 3 minutes he probably loses. (The same holds true for White & Steveson as well).
As of today he is still too cautious and extends way too much respect for some of these guys, with last night being an example, until far to late in the match. Sure he handled a much bigger Jennings, but that first period was a yawner and Cassar has an advantage in neutral over almost anyone not named Gable. He needs to exploit this early in every match.
The blast double is probably off the table vs Stoll. He's to big. It will be difficult to ride him out and Cassar might have a challenge getting out from under. The first period will be key.
If he targets a single leg to a certain knee 3-4x in the first period he will win by at least 3 points.
