Looks to me that Kovalchuk lost his RW, not his LW.
AFAIC, the position that they actually play is immaterial, as long as Yahoo (or whoever) is going to list them at a given position.
So, I would consider Kovy an LW until the day comes that he's listed otherwise.
12 H2H w/ daily changes.
Keep 6 (5 F/D, 1 D/G) Start 2C, 2LW, 2RW, 3D, 2Util, 2G
C: Getzlaf, Bergeron, Roy, Boyes (RW)
LW: Kovalchuk (RW), Vanek, Lucic
RW: Gaborik, Callahan, C. Stewart, Tarasenko, Chiasson
D: Yandle, Doughty, Goligoski, Carlson
G: Fleury, Varlamov, Markstrom
