Slava is legit choice for the ballot, imo. He was a point a game player last year, even slightly better point totals (81gm-80pts) than Kovy (82gm-76pts) last year.
If Kovalchuk continues with his play so far this season, he'll get voted onto the starting line-up without a doubt.
If I was the one choosing the players on the ballot, I personally would've made a statement by not putting on Kozlov or Hossa, and instead putting on Enstrom, or Little. Kovy, Enstrom, and Little have been our top 3 players this year, and therefore, if anyone on this team is going to be an all-star, it has to be those three.
