Well to be a legit top 6 player Matthews has to take out guys like Crosby, Malkin, Benn, McDavid, Ovie, etc. A guy like Eichel could also make a case to break into the top 6.
That is going to be very tough and unlikely for him to achieve. Doesn't mean he won't have any issues landing somewhere just outside of that. But to break into the tier of the best handful of players in the world, it's unlikely.
I'm not sure where "top 6" came from though lol.
Of course it will get better. Still doesn't mean he is going to become a Selke candidate. I'm not saying he couldn't. But again, tempered expectations. It would be a miracle for all 3 of Matthews, Nylander and Marner to become top 10 players in the NHL. Some Toronto fans act like that these players are a lock to all be that great and its ridiculous. The expectations from the three should be set at getting three good top six players and one elite 1C. That would be a win for Toronto. All three of these players have a long way to go to accomplish that. A lot of players tear up juniors, AHL, and even go as far as showing tons of skill in the NHL. But for some reason or another some players who clearly showed a ton of skill in the NHL can never quite become a PPG elite player.
I mean look as close as the recent past to the Toronto roster. Kadri, a 7th overall, who instantly scored at a PPG rate at the AHL. Kid is currently a really good hockey player. I like him and was rooting for Toronto to lock him up long-term (they did). To this day he shows flashes of high end talent. But he has never been able to bust over that hump. This happens a lot. I'm not going to get into the debate of the current prospects being higher caliber than Kadri. But a lot more was expected from Kadri and the point is. any of these prospects could meet a similar fate.
I play in a competitive dynasty league and have Nylander as well as traded for the 1st overall to get Matthews. I even have Kadri for SOG, hits and solid points. I love Nylander and Matthews as players and really need them to pan out. My point is that some fans around here just need to temper their expectations a little bit. That's all.
