Absolutely not defending Bogosian for how he's played this season (well below par in general, and that's me being nice), but I'm trying to take a look at what factors have caused him to play badly, and how (or if) Doughty and Pietrangelo have had to face those same issues. The closest comparison is to Doughty, and as far as numbers go, Doughnuts puts Zach to shame. There are outlying factors that make their paths very, very different ones so far.
