You seem to overestimate Rantanen like there is no tomorrow. And at the same time I have realized that you seem to have an agenda against Aho. If after how all Finnish players have played so far in the first two games you can really think of cutting one of the clearly best players in the Finnish team, you are not thinking with your right mind. The only forwards who have played even better than Aho, have been Granlund and Laine. Aho has definitely been on the same level with Komarov, Barkov, and Jokinen. Koivu has been a slight disappointment so far, and Pulkkinen has been almost useless, and Sallinen has been a waste of his roster spot, even in his role. If any player should be switched for Rantanen, it should be either Pulkkinen or Sallinen. Koivu can't for sure be even considered, and he will anyway become much better the longer the tournament continues. Swapping also Sallinen would only make sense if Lajunen as a center would substitute for him. So there is not really much other options than to ditch your golden boy, Pulkkinen.
Your agenda and devaluing against young super talents is really getting tiring here. Before the tournament you were seriously saying that Pulkkinen should be the number 1 sniper option compared to Laine and even questioning if Laine would have a spot in the playing roster. Maybe youth doesn't really mean that much as a bad thing as you seem to think? Have you paid attention how Laine has been really much better than Pulkkinen in almost everything. Pulkkinen doesn't have the drive and the hunger. And for sure he doesn't have the talent that Laine has, except to some extent a similar slapshot and onetimer. But no wrister and not even close the hands or passing skills.
Wake up call again! You don't ditch a player like Aho from this Finnish roster, as he is the best skater (with top speed Pillu has the edge, but otherwise), best defensive forward (with Barkov) and best passer and playmaker (at the same level with Granlund and Barkov here).
The only thing I agree with is, that maybe Aho should not be playing with Koivu and Granlund, although I can see that Aho-Granlund might have some chemistry, but the whole line doesn't seem to work as well as I would hope. Aho could be better used with Barkov and Laine, and Jokinen or Komarov could probably fit better with Koivu and Granlund. Or the other option would be to put Aho back to Koskiranta's line and put Pyörälä to the 4th line instead of Pulkkinen.
Thank God at least even Koojii is not so conservatively thinking that he would be ditching Aho. I can't in fact think of any real hockey expert doing that...
