Kadri wasn't going to replicate last year... players almost never do, especially if it happens past 30. More or less, the Avs simply didn't feel the 2C spot was enough of an issue to solve.
Call me crazy, but I think the Avs could have had a Cup prior to last year if they were more aggressive. Teams rarely push hard enough, early enough in windows. I think the patience from years prior hurt the chances of winning multiple cups in the window. That said, winning even one is a huge win and makes the whole window a success.
Again though, my worry is the Avs simply don't value center enough and they combine that with being poor evaluators at what skill sets work at center. Newhook is not the only or last smaller, average to above average skating center the Avs have tried to fit into the 2C role. I think the pro scouts tend to be very good and can solve issues... but those issues are simply like taking a 2nd or 3rd mortgage out on a house. You can do it and it solves the bills of today... but those bills come due. Plus when you end up in a situation where assets have declining value, it hurts the ability to solve issues with said assets.
When we look at what assets the Avs have to solve the 2C issue, you have 23 1st, 24 1st, Newhook, OO, and Behrens. Unless you package them all together and bet the whole farm, you're unlikely to get more than a rental. The other piece is really Byram and he could singlehandedly solve the issue if he get a clean bill of health. Now I already hear the calls of G here... but by the day, his ability to solve the 2C spot is dwindling. Takes a team that doesn't care about size and is willing this shake off injury concerns, playoff performance concerns, and regression concerns... that's a small pool for a 2C sort of deal. For a 2nd line winger, you could very easily find a deal for G.
Avs should be looking at the skill set of Newhook and how it just doesn't work as a 2C. Center is too difficult of position to just cover up and win without. It has happened, but it is rare.
