As a self-admitted massive Mangiapane fan, I don't think I'm the best person to ask. In my mind he wouldn't be available since his age has him lineup with the Flames contending, OR the Flames rebuilding with him as a top 6 player. He's on his first year of a two-year deal at ~2.3 million iirc. So a pretty solid deal that ends with him as an RFA with arb rights. Can't think of a deal that makes sense for Mangiapane straight up unless he's involved in something bigger, which I'm sure the Isles wouldn't want to do with their current success
