Hey, I am one of the few lightning fans that like Tanev. He's been my favourite Canuck for years. I watch him all the time, me living in Vancouver, my whole life. I've been a Lightning fan since 98, but because of my family watch Canucks games, regularly, I know very well what he is capable of when he is on the ice. I value that. But its like I am beating a dead horse here, the fact that we can't even say he'll be healthy for a season because it would be a lie is a problem. The guy whether he is made of glass, unlucky, or plays dangerously, matters not. Just like Canuck fans say he is an elite 2D (Which I agree), the fact which is his complete counter argument is "he maybe elite, but he won't be elite on the ice because he is injured" hurts his value tremendously. You're basically trying to sell a Mercedes with dents, an engine that needs repair, a new transmission. Is it a Mercedes? Yes, a nice one. Does it require work? Yes because you treated in poorly and its banged up. Does that mean you can ask full price? Nope.
I said in previous threads that Vancouver and Tampa are not good trading partners. Because to us Foote offers something major. Cost control for years and possibly a future pairing partner for Sergachev. Tanev helps us now, but we Yzerman doesn't gut the future for the present. While he traded the firsts for McDonagh, and Howden and Hajek, both were expendable because of players like Cernak, Masin, and Cirelli. The firsts suck, but we are typically terrible in the first round aside from Vasy. If the ask is Foote and a first, or like someone who was completely out to lunch asking for Sergachev or Point (Rangers fans tried this), then hold on to Tanev and don't trade anything for him.
Tanev helps but doesn't push us over the top. And from the sounds of it, Tanev won't bring in want Vancouver wants and are happy to keep him.
Side Note, I don't think Juolevi makes the team right out of camp this year. Maybe later in the year, but not out of the gates.
