I don't see why people keep penciling in Ras to the lineup over Zadina. Zadina is much more NHL ready, though they both should make the opening day roster.
Also if you want to talk about tank, this is how you tank:
First, sign all the vets. No rookies this season. Period. They can overachieve, washed up vets usually don't and are much more likely to underwhelm. Second, gift AA with top line time. And in the same vein don't ever do anything when he or Mantha float. In fact, reward floating. Every shift they float, they get another shift, and cookies. In fact, milkshakes after every game. AA and Mantha should be 400 pounds by December (1000 pounds of fun line right there, marketing guys better be listening). No more gym, just food. And Larkin? Sounds like a third line center to me! Nielsen should be top line center, followed by Helm, then Larkin then Z. Playing Z for 20 minutes a night is a way to get more points, we don't want that. Finally, Coreau should be the starter right out of the gates. And new rule, he can't use a goal stick, he can only use a switch he cuts that night right before the game and it must pass inspection. No raccoon bites=no go.
That was just for fun, but anyone who thinks playing kids=tank or somehow it hurts their development has it backwards. The only positive way forward for this team is to play any kid that is close to NHL ready. Detroit needs to know who is going to be an NHL player and who is going to bust as quickly as possible. The last decade has been marred in the 'over-ripe' mentality that has left Detroit counting their chickens because they assumed that letting a player languish in AHL/CHL/NCAA would mean they would develop more. Instead what they had was a lot of rotten fruit. Its time for that to end.
