I saw some really nice things from Bjork, I think, much like Donato, he`ll be a prospect who will need to improve away from the puck but both are so young, and they both appear to be very teachable kids so I`m not worried.
To me, in this day and age, if your team isn`t strong up the middle, the rest is null and void. Obviously stability in net and on the blueline are all big keys but if you have only one C who opponents need to be concerned about, your already behind the 8 ball.
The Leafs, IMO, will likely shift Nylander to the dot next year where I think he`s more comfortable however, not so sure about his game defensively as I haven`t seen him enough in that spot to assess.
The Leafs biggest challenge might be due to being forced to have an eye on the cap. They have some youth who`ll be cashing in big time and I don`t think they can go big in the UFA pool and I`m not convinced that Babcock is a guy who is one players line up to play for.
