At the same time over 1/2 their roster is young drafted players that they have aggressively pushed into the lineup over the last few years. Most have started at the bottom, did what they could, showed some promise and were given more opportunity. Nic actually came along in favorable conditions and had fewer players in his way than picks that came after him that were able to carve out roles.
Very few skilled players started at the bottom Bogo.
Morrissey top 4 right off the bat with Buff
Ehlers started with Scheifele and Perrault
Conner started with Perrault and Armia
Laine consistently in the top 6
Only Roslovic and Petan started at the bottom and Roslovic has clearly done less then Petan did with his top 6 opportunity.
Also Petan has been quite good in the past with Copp and Armia or even this year on the fourth line, it just comes down to Maurice wanting a different elements for that role for good or for bad.
