One of the toughest challenges for any NHL rookie is maintaining a high level of consistency against bigger and stronger players on a nightly basis and over an entire season.
Buffalo Sabres center Jack Eichel and Calgary Flames left wing Sam Bennett are discovering it's tough to duplicate the success they each had at the collegiate and junior hockey level, respectively, in the best League in the world. It hasn't discouraged them, but each knows patience and a little persistence will pay off in the end.
It isn't as though Eichel or Bennett are struggling this season. Rather, it's more of an adjustment period.
