One thing people on this forum are bad for are overhyping our 'shiny new toys'.
Prospects like Kapanen and Johnsson have shown signs of being good, but they've also made some pretty bad mistakes.
Kapanen in particular has been on the ice for 7GA (5 at ES) and is a -3.
Johnsson being staying in the lineup, but he could be injured after being hit hard last game.
If Komarov is in, he won't have the 'high abilities' that Kapanen or Johnsson have, but he also isn't prone to many mistakes that Kapanen and Johnsson have shown so far either.
I'd prefer to keep Komarov out of the lineup, but its not the end of the world if we have him on our 4th line...
