The main difference is that I don’t think Jiricek has true top-pairing upside, so he has a more limited projection than the top six defensemen (who all definitely have top pairing upside, though some are riskier than others).
Jiricek is very much a “jack of all trades” type of player. Above average at everything, but no outstanding skill. Compared to his brother David, who has an elite shot, I just don’t see any particular aspect to Adam that I can project to a top pairing level. But if he can stay healthy he’s got a really good shot at playing in the NHL, and even even if he doesn’t hit his middle-pairing upside, bottom pairing two-way RHD’s with 6’2” frames are valuable.
He’s got an excellent shot, which gives him good scoring potential. To me, MBN seems like everything we love about Zetterlund but dialed up to 20. Bigger, faster, better at everything.
