I didn't know about the above players either but I felt convinced that Mallet wasn't the best pick at that particular spot.
That being said, I also wasn't aware of the bolded which you just mentioned.
Sometimes it is really tempting/easier to make 'outsider observations', like I did, and you're right - it's far too early to make judgements. From the little I've heard of Mallet, it seems he has "character", which before reading your post, I thought, at the time, was a flimsy reason for going 'off-the-board' for. I hope he does well though, genuinely and becomes someone like Burrows who is a major part of this team.
It's understandable if one hasn't watched him play on the Wolves earlier this season. But the impression that I got from watching him play was that he is a smart player with good hockey IQ, and that's what gives me confidence that he'll turn out to be a good pro.
I know there's the history of us doing poorly in the Q but I think his overall combination of attributes - quite a few of them too - will allow him to succeed where other draft picks have failed before. Likewise with Grenier, I was skeptical of the pick but now it's looking like he has some potential too, so I'll be patient with Gillis' drafting and give them time.
Btw yeah, he really does seem like he could be another Burrows, except bigger and tougher to boot.
