Our herd of fans are too worried the past = the future. There are many different examples of good and bad development from the Habs and many other teams.
The blanket statement of "send him to the AHL" is flawed but once again, posters will cherry pick past examples with the Habs. People forget Suzuki started in the NHL at age 20 at wing. Same type of thinking today would have said to send him to the AHL to play center so he can "develop properly" as a center.
At the end of the day, good development comes down to the players hockey IQ and their will to put the work in to overcome the obstacles. The team can only do so much. Said this for years now and there is nothing anybody can say to derail it.
In Slaf's case, it's a matter of maturity towards managing less time and space. Less time and space exists in the AHL too! So he can develop in either league but the negative is if we play him 12 min a game or less in the NHL where in the AHL he can get 18-20 range. With this Habs roster, we will be rolling lines and monitoring the youth's opportunity and performance. It really is fluid week/week.
Suzuki developed from Wing to a Center at age 20 in his 1st season playing about 14-15 min a game. Dam... could have played 18-20 mins a game in the AHL as a "center". Would be a better center today eh?
