File this slide under the category of longshot.
Cam Talbot, Tim Erixon, Dylan McIlrath, 2011 first-round pick J.T. Miller, Kris Newbury and Casey Wellman are all with the Rangers, serving as the team's "taxi squad" by skating with the team during practices.
It's highly unlike any of the five aforementioned skaters see any time in the playoffs unless a catastrophic injury occurs.
Of the forwards, Casey Wellman—acquired from the Minnesota Wild in exchange for Erik Christensen—would be the best choice to step in right away if needed (22 points in 31 games with the Whale and has 41 games of NHL experience).
