Given Zamula was passing to the wrong team, and Braun has a much better sense when and how to pinch, I don't think playing Braun over Zamula has a big impact on scoring - Zamula is not an offensive force.
The problem with lines is that they simply lack centers, Frost is getting good wingers and still not producing, Cates is learning on the job, Sedlak is game but ideally would be an above average 4C, and Brown is, well, Brown.
Frost, last 10 games:
Tippett 85 minutes
Farabee 51 minutes
Bellows 29 minutes
MacEwen 18 minutes
Laughton 16 minutes
Deslauriers 15 minutes
Hard to play him with anyone else with TK and JVR out of the lineup.
During that period, xGF 40.31%, GF/GA 2/7.
Those are Thompson like numbers.
Cates is also struggling, xGF 40.09%, GF/GA 5/3.
MacEwen 65 minutes
Hayes 61 minutes
TK 34 minutes
Laughton 25 minutes
Farabee 15 minutes
Deslauriers 15 minutes
Tippett 13 minutes
