No they're not. Watching the Colorado Eagles, Guenin and Cliche would be awful even on that roster.
Personal opinion. Maybe you think they are, but I wouldn't want them on the Eagles roster.
I don't want Mike Ribeiro on the Ducks, but he is still clearly an NHL caliber player.
Nate Guenin has had NHL contracts with more than a handful teams for a nearly a decade. He has been a solid top 4 guy in the AHL the whole time, otherwise teams wouldn't call him up every year. NHL teams don't give contracts to "below ECHL level" players for a decade or call them up on a yearly basis. And AHL teams don't make them captain of their team.
Looking at the Colorado Eagles roster, I recognize a handful players who I remember from the AHL or who had NHL contracts. Loic Leduc, Teigan Zahn, Sean Zimmerman, Darryl Bootland, Nathan Moon... If these guys can make the Eagles then so would Guenin. I've even seen Zimmerman, Zahn and Guenin all in the Ducks system just a couple of years ago. Guenin is clearly better than both.
