I prefer Tatar for his enthusiasm and hustle, but I think Nyquist is the better player. Better defensively, better playmaking for others and he just has a higher hockey sense. The downside is that he is more of a confidence player and thus more likely to blow hit and cold.
Larkin is the safest bet, (such smooth progression) and at the moment has little competition for his projected role. Mantha has an upside that may be even greater but a few more question marks, and may have more competition. Neither will see more than a handful of games this year, just as mantha was very unlikely to make the team even before his injury.
Looking at lower draft picks, AA is the one who looks most nailed on at NHL level and probably has the highest ceiling, but I think Holmstrom has an alluring mix of intensity and smarts.
D-wise, I think all are 2nd/3rd pairing guys, but I love marchenko's gone and think he has upside...
Also using the mutual shut down (edge to hank on an inferior team) in 2013 to compare peaks is not that great, as its 3-4 years after his peak, struggling with back problems and often stuck with at least one offensive vacuum.
They are very similar players, and right now Toews is the better, but at his best hank could just do more
