Whether you like the three 2015 1st rounders or not (personally I don't love or hate any of them, all three are kinda "meh"), the fact remains SEVEN players drafted behind them in the 1st round in picks 16-28 have played at least 1 NHL game already. That's a fact, not opinion.
Meanwhile two of Boston's picks (Zboril and Senyshyn) didn't even make the Boston brass flinch about keeping them around into the regular season, matter of fact both were fairly early cuts, so it wasn't like Boston management had pause for thought regarding either.
Debrusk pushed for a job and looks like he might have a decent NHL future.
Thankfully the Bruins found Carlo in the early 2nd.
