There was talk at the trade deadline that the Hawks had interest in Petro but it never happened. They have around $5M in cap space. Saad and Kruger could eat up $7 or $8M, then they have to either sign or replace Richards or Oduya. Maybe they get them for a song, but I doubt it. Teuvo I believe has been playing on the wing in the playoffs, but he is a possibilty as the 2nd line C. That is a big if as he is not a solid F/O guy. Oduya could command close to $4M and Richards could get $2.5 in UFA. Timonen is probably done + they need one or two more guys for their d corp depending on what happens to Oduya. Pukka may be ready, but that is conjecture.
Sharp is definitely gone and Teuvo or Panarin will probably take his spot. Bickell's $4M may be tough to trade with only 11 and 14 goals his last 2 years. They need someone still on an ELC or small RFA contract in the Sharp trade and that could be either Tro or Petro. I'm not sure if Sharp gets his choice of teams in a trade, but I doubt he would be interested in the Coyotes. Is Seabrook an option if Bickell is untradeable?....yes.
