they also sent Kravtsov and Chytil down to juggle the roster
I never said IN A VACUUM Boo was a 1C for them or anyone else.
In a vacuum his projected top mark is 3C, MAYBE 2C in a good fit.
However, as I am on record noting, the fit here is Kreider. Nieves on paper is an ideal complement to Kreider (driver of possession) and the correct RW who is a finisher w/acceptably high scorer skills. That should be Zib, not b'c he isn't good as a 1C, he is, but b'c we have other first line options, and we can return the righty shot Zib to bookend with lefty Kreider, which is known to work well in the past. Nieves has the size, superior speed, reach, passing skill, and defensive prowess [as seen by a very good +/- for a 4th liner w/no PP, and scrub Ws who are black holes for scoring, suppressing Boo's own point totals]. The dominance of these Ws w/some support presence by Boo, and better Ds [Fox, Trouba, etc] would exploit offensively while Nieves could be counted on to get back defensively if there is too much pinching/overreach.
Like I said, Nieves should be attached to Kreider. BK, Before Kakko, Chris was the undisputed 1LW. With addition of KK, Chris is 2LW, so Nieves, should be 2C allowing righty shot Zib to 2RW. Zib on 2nd line strengthens that unit.
Ist line? IMO should be KK-Krav-Panarin. KK may ultimately play pivot, and maybe not, let's not rush him and while all these guys can do what chemistry dictates/drawn up plays suggest is best, start with lefty shot at LW, breadman switches from LW to RW, again, mostly for purposes of faceoffs, etc so not using weaker side on draws. Kravtsov is phenomenal vision and good other skills, has played pivot briefly very well in high level international play, and only adjustment to NHL is to get acclimated to size of rink, which he can handle physically, but needs mental adjustment contrary to his initial impulse, which he will revise with experience.
Chytil and others are other possibles here, but I think we are best off pushing him to third line, strengthening that. Sell Buch high.
trust that covers it.
