Marner is a lightening rod for criticism because he is a bit emotionally immature. On most nights he can pull you out of your seat with his dazzling skills. On other nights though he can make you turn off the television in disgust. I think if he simplified his game he would be even more devastating - same for all of the offensive dynamos on this team.
Getting Marner fifth overall was one of the better decisions this franchise made and it cannot be overstated considering how many high profile misses the organization has had (Luke Schenn for example).
Obviously I am not happy with this team consistently bowing out in the first round, but it is certainly preferable to those barren eras where we had to rely on other team's scraps and left overs to barely contend for the last playoff spot. For once the Leafs have a core of strong players that they have drafted and developed - Morgan Reilly, Mitch Marner, Auston Matthews, Rasmus Sandin, Timothy Lilgren, Pierre Engvall, William Nylander, etc.
