How I see it;
- Dach has the highest potential of the three - that close to Ryan Getzlaf if everything works out, but will most likely not reach it. 30/70
- Cozens has the best floor to become a very good second line centre, but I do think there are limits in his talent level. 50/50
- Turcotte has the best chance of having high-end potential and actually reaching it. 60/40
All three probably become low-end 1st line centres for their respected teams akin to Matt Duchene or Sean Monahan, but I still believe that Turcotte has the best chance of surpassing and giving a team a fantastic 1-2 punch similar to Penguins (of course not as good). Dach still has issues of even becoming centre, but if figures out some things in the next couple of years he should be lethal. Cozens has some puck skill limitations, but his speed and shot should be quite a combo once he becomes more mature in frame and just experience (perhaps you can say that there is hidden talent with him which reminds me of Landeskog).
Not sure I agree, I am more with Hench is that BPA is important, but when you have this many players bunched up and this many centres you gotta get a centre.
