According to Josh Yohe, another name to keep a close eye on is Bryan Rust, with the top Penguins insider revealing that the expiration of his NMC will make him a very appealing target for rival teams in the off-season.
At 32-years of age, Rust has posted 21 goals and 47 points in 55 games played this season, so he can clearly still contribute at a very high level, and with a palatable $5.1 million salary cap hit for a further three seasons, he'll be in very high demand.
Whether or not the Penguins will listen to offers on Rust is another story to work out in the summer, but for now, he's a name to keep a close eye on over the summer.
