Interesting how this thread is going. The first response is about trading "our only true shutdown defender", then the rest talk about how much more we would have to add to the deal. Agian we have no idea what it would take. E and tatar? sure. There are many possible ways to do this. But if it can be, do it.
Look at things long term. E is a UFA after next season. he is making 3.25 million per now. How much is it going to take to resign him? i would guess 5 years and 25 million. Is E worth 5 million per season? No. he is a 3/4 not a 1/2. With Kronwall, Smith, Kindl, Dekeyser, Lashoff, Q, Sproul, Oullett, Nicasctro, and de haas still in the system, we have plenty of Dmen ready and on the way. More than enough talent to replace E.
Now go look at the forward group. is there a single future #1 C in the group anywhere? No. not even close. In fact some are suggesting we resign Filppula for 4-5 million per as insurance if datsyuk leaves. Courturier on the other hand is a true future #1 C. For the next year+ he would be our #3 behind dat and z. learning the trade with no pressure. In 2 years, if Datsyuk leaves he is our #2. in 3 years our #1.
HF had Courturier rated as an 8.5 prospect. They compare 8's to Spezza, marleu, and Richards. 9's are compared to E Staal and thornton. So Courturier is somewhere in that range, all of which are/where point per game players.
All that being said, will this ever happen? no. Honestly Holland doesn't have the guts anymore to even try.
