Kravtsov was only rushed in the sense that he should've stayed over in Russia for a few years before coming to NA. He wanted to sign his ELC because he thought he'd make the NHL team. The front office should've told him that wasn't going to happen, but if a player is so set on doing something that he had a very small chance of accomplishing it's hard to blame the team. At no point has Kravtsov actually made the NHL team out of camp, so it's hard to say they rushed him to the NHL. He only has 20 games that came towards the end of the 20-21 COVID season.
Lafreniere was not rushed. He looked like an NHL'er his first year. We just didn't have a big role available for him, which is why stat-watchers will claim he was rushed. Thats what happens when you play for a good team. You can't always afford to give your top picks 20 minutes per game and PP1 right away. I'm hoping he eventually is given a bigger role because as anyone should be able to see from late on in the season and the playoffs he's a more effective forward currently than Vatrano and Strome.
Chytil wasn't rushed either. He got 9 games that first season, and when he wasn't ready, he was sent to the AHL. Isn't that the epitome of not rushing a player is to send them back when they aren't ready? I don't know what the basis is for saying Chytil would've developed better somewhere else. He's not done too bad. Like Lafreneiere he has been given a small role, which hasn't always suited his game. Last season he was great. This season, he's had awful puck luck, although it's started to normalize later on in the season and the playoffs. You can't expect someone who is 3rd line and sometimes PP2 and sometimes not PP2 to score 45-50 points. Like Lafreniere, this is what happens when you are a first round pick on a team with good players ahead of you. Chytil is only 22. Plenty of time for him to be a big scorer. For now, he's a 3rd liner on a very good team.
Kakko might've been rushed. That one I will agree with you. His first year he should've been in the AHL. It was obvious very early on in that season that he shouldn't have been in the AHL. It would've been easy to send him to the AHL, but they didn't. It is a little hard though to send the 2OA elsewhere. It's a lot easier when the player makes the decision for you and plays college hockey or doesn't sign their ELC right away. That makes the decision for you. There haven't been very many 2OA's over the years where the team signed the 2OA right away and had them playing somewhere other than the NHL.
