You got me beat, he definitely should have been there.
Central scouting has him ranked 74th amongst NA skaters, I think they're underating him.
Good skater, very hard hitting and in your face defensive checker. His offensive game has exceeded all expectations this year, he really generates offense with his forecheck and boards skills, Downie also has a quick release on his shot. Future pest (to say the least), who's offensive upside is growing.
I watched him enrage Mike Richards to the point that Richards actually went into the Spitfires penalty box to try and get at Downie (Richards was then suspended). The next game Windsor played against Kitchener he drew a headbutting penalty against Valabik. Aside from driving opposition players nuts, he's just a non stop sparkplug on the ice and doesn't take a shift off.
You could tell from his play last year (as a rookie) that Downie was going to be quite the player, I personnally thought he was the 2nd best forward for the Spits in their playoff series against London. With 47 points in 43 games this season, his offensive game has come along much quicker than most thought it would.
