Jussi keeps his lines together (rather than swapping out a zillion times...) so he has some hard choices to make for today's game against Erie. The two players that could be affected by the insertion of Mesar are Swick and Lam.
With Swick up on the top line, you have that big body in front of the net (and goalie) causing havoc. This is much like Martin on the 2nd line. Moving Swick to the 3rd line might seem like a demotion if you will - especially after scoring two recently. But Swick himself says that he's no Razer and Missile. He knows what his job is on that line.
Jussi said that Lam should have been selected for the Under 17. He is high on Lam's talent and ability at such a young age. Lam has been impressive from the pre-season right onwards. He's tied for 2nd in Rookies. Just the same, he certainly could make the 3rd line a dangerous one. His time will come and I think he will take on whatever role Jussi gives him.
I'm leaning towards leaving the first line alone, inserting Mesar on the 2nd line, and moving Lam to the 3rd line. If Mesar works his tail off (and I believe he will), the Rangers will be even more deadly starting tonight.
