The thing I remember about Juneau in the 1995ish range is takes about how, he's a very good playmaker, but he's probably not ever going to score 30 goals again, because that was Adam Oates's doing. And that's fair enough, he never did. And then he eventually stopped getting so many assists, but he was pushing 30 by then, so that's really not all that weird.
I think once you start adjusting for bits of context to Juneau's career (an Oates-related goal-scoring spike, the 1992-93 scoring explosion for top players, the lockout), his career curve from age 25 onward starts looking very normal - a point per game playmaker who drifts down to a 60-point pace by 28, and usually a 40-point pace in the first half of his 30s while providing good defensive play and then done by 36 - what's more normal than that? And it'd look even more normal if one granted him a few ramp-up seasons in his early 20s. He spent those years in college, and I'm not sure he even qualifies as a particularly late bloomer - he had been drafted 5 years before his big season (at 20, mind you), and was absolutely ripping up the ECAC circuit to the tune of 70 points in 30 games for several seasons, and given his 16 points in 14 games for the Bruins after graduating, there's no reason to think he wouldn't have had at least one earlier season as a fairly high scoring forward.
Before looking at him a little closer, I had been thinking of him as a rich man's Travis Green, but I'm not even sure that holds - I've said before that I really don't understand what higher-order skills Green was good at, despite being intimately familiar with him as a Maple Leaf. Usually, like with Juneau, you can see flashes of smarts or soft hands that only come out on the power play, once they've settled into their third line years (Tyler Ennis is another guy who you could say that about for the Leafs). Nothing like that for Green that I can remember.
