I think it's pretty safe to say that even with only 8 games played so far that Sergachev is going to stay up for the rest of the year. Calling it now. He has 6 points in 8 games which is twice as many as Hedman! His team is currently first place in the entire league. No way they send him down.
I predicted Tampa to make the playoffs this year but they are on another level right now. They even have a good chance to make the finals or even win the cup this year. They have a real #1 elite C, Elite #1D and very good goalie. Add in a great coach, great depth and with Stamkos looking rejuvenated they will be very hard to beat.
