Did Engren just outplay Vehanen? I havent followed this series close enough, but wow such goalkeeping depth in Prague.
In my opinion - he has. In Jalonen's opinion, I think, he knows he has a very good goalie in Engren and he can absolutely trust him even for an important games but if there was a winner take all match tomorrow he would still go with Vehanen because you know, he's Petri Vehanen.
The reason Engren started the game 3 is pretty clear - Vehanen needed a bit of a rest and he couldn't just keep playing back to backs so it made sense to rest him for game 3. Also he just lost the match in Prague so he benefited from a bit more bounce back time.
I guess reasons for playing Engren in game 6 are a lot similar and that line of thinking was only encouraged by the great game 3. He gave Vehanen time to rest and keep him fresh, both physically and mentally, for a possible game 7. Playing in game 7 after a recent loss to the same team isn't the best place for a goalie. Going with the backup in game 7 is extremely controversial for a coach so the way Jalonen handled is goalies makes total sense.
I think depending on how the series go, they will split time close 50-50 against Loko. At least in first 4 matches.
