Why Jiricek. He's trash. No time to develop him.
Provy would be awesome
In watching Jiricek there were multiple times I watched him and he had the look of a guy who has been in the league for much longer like 4-5 seasons, with really solid fundamentals. Other times he very much struggled, but I would not be shocked to see him fast tracked and produce at a similar level to Bowen Byram when he won a Cup.
I'm not going to say he is the answer cause a soon to be 21 yr old d-man rarely is, but I will say I do like him quite a bit and he is one the few players his age that are struggling that I wouldn't reject outright.
------------------------------------
With respect to the other names I view Provorov in a similar light to Chychrun, he's got a lot of skill but also brings a bit of chaos, I'm always a bit hesitant matching this type with Nurse, I prefer only one of this player type on a pairing; though if it works its got big home run potential.
Pettersson I view similarly to Chris Tanev, just a plain safe steady d-man, I'd say the central difference though is Pettersson's game while he still does hit and block shots, he doesn't take as many dumb risks so tends to be more durable.
