This is only speculation for the moment, but James Iacavone highlighted an important detail. There haven't been any Flyers scouts at the Avalanche or Eagles (AHL affiliate of Colorado) games recently. Also, in the last few games of the Flyers, Avalanche's scouts weren't in attendace.
With that being said, I agree with him when he says that Giroux isn't a necessity for Colorado, as they need some bottom-6 forwards more than a top-6 forward.
With the things we heard about what Joe Sakic wanted to give for the Flyers captain, I think there are far more better options, like the Wild, the Blues, the Panthers or even the Hurricanes.
