Sometimes people forget the season is a marathon, not a sprint. While we don't want to get too far behind, usually Cup contenders are the teams coming on later in the season. Even in '11-'12, we were blazing hot in November, December and January, .500 thereafter, and lost meekly to the Devils in the ECF.
I think Pyatt is absolutely way too slow doing everything to be in the NHL, and Boyle can't stand upright half the time (at least Boyle does have some usefulness as a 4th line winger and PKer, though). Nonetheless, better early in the season to develop Miller, Fast (wasn't it Fasth last year?), Kreider, etc., than to play them as grinders/checkers with crappy offensive players like Pyatt/Boyle et al. on the bottom lines, where they have no chance to develop, and get benched every time they make a mistake.
I watched JT Miller play in the Junior Championships last year a lot. I understand the competition wasn't on the same level, but he played with panache - aggressive, not afraid to shoot or take chances. I'm seeing a timidity to do things instinctually now that I think comes from the fear of making a mistake.
