I'd agree with Versteeg being the weaker of those 3..
Rene Bourque - always an injury concern but produces in spurts across all cats
Callahan - playing excellent right now but the big boys for NYR are all injured - dunno if he can keep it up when they come back
Cullen - prolly most reliable name here and least flashy, has opp to make offensive role with the Wild
Williams - always a good scorer but well known injury history
Moulson - rides shotgun w/Tavares. solid pick
Kopecky - uncharted territory for him, getting 1st PP time with Hawks
Stafford - Sabres need scoring from somewhere & seems like every year I'm wondering if this'll be the year he goes off.. doubt it
Depending on your willingness to take risks - the fact that you're willing to burn one of your 2 season long moves tells me you're ok with that. Williams and Bourque have the potential to net you the most points but they're both injury risks. Outside of that, Cullen or Moulson are prolly the safest plays but do you really wanna play it safe?
