When we signed Bunting as a hopful top 6 guy he was a notably late bloomer coming off a partial season where he impressed with his goal scoring. That was 4 seasons ago, McMann is currently in the same situation basically.
Both Bunting and McMann are currently 28 years old (Bunting does turn 29 in a month).
This is why I'm a little leary of expecting much from McMann. I like him, dont get me wrong, but from a traditional development curve standpoint for his player type and role he'd be a vet looking to see if he can hang on to his NHL career for another year or two. But of course he hasn't taken a typical path. The usual problem for this player type at this age is if the body can hold up. But McMann hasn't gone through the grinder the way most NHLers have by 28. He has had some injury issues though.
As long as we can get two decent years out of him, that's great.
As it stands now... without trades, we have Nylander, Marner, Domi, Knies, Cowan and Grebyonkin in the top nine. Maybe Robertson sticks... or not. That's seven guys, for six top 9 winger spots.
Maybe he solidifies a 4th line position when Knies, Cowan and Grebyonkin are fully developed... but it's not like we are dependent on further growth from McMann.... and I like the guy too.
