I suspect we'd agree many things contribute, and that to excel we need to improve them all. How I see these two incidents:
1. Once the ball hit the deck, Starling's prime focus had to be on helping us take that huge advantage. He not only totally nullified that advantage but gave the opposition two very, very cheap points.
2. Same with Kapow. Once the ball bypassed French, and even more so when it hit the deck, Kapow's prime focus had to be on pulling out of the big hit. Even a simple grab of French would not have drawn attention. With that obsession to hit no matter what, he nullified all of his work and all of his teammates' work for the entire game. He pulls out of the cheap shot, we win the game. Simple as that. It was as dumb as that shoulder charge that got him suspended for 3 weeks and which may have cost us wins in those games.
Lussick used to not control himself in situations like that. Now he does and plays with highly intense but effective aggression. Starling and Kapow need to learn from Lussick.
