Ivan Fedotov
Now this is a technicality. By NHL rules, Ivan Fedotov is not considered a rookie because he is 27 years old. However, for this list, we are looking at him as one. He has only played three games in the NHL. The numbers are ugly, but it isn't fair to judge him on those. The team was gassed, trying to stay afloat in the playoff race. There wasn't much time for Fedotov to learn and adapt.
Add that into playing in North America for the first time and learning a brand new culture. Especially at a critical time in the Flyers season. This next season will be a good look at Fedotov and if the long wait was worth it for both him and the team.
He signed a two-year contract in the offseason. And while the money might be a touch higher than some like, it can't be based on anything he did in his limited sample size. With an offseason to train and a fresh season ahead of him, Fedotov should yield much better results.
He enters the season as the likely backup to Sam Ersson unless things go wrong. Fedotov is likely to get a handful of games throughout the season as the Flyers should try to avoid burning out Ersson once again. Now, that will depend on how Fedotov performs. If he excels, Philadelphia can afford to rest Ersson on more occasions. If not, then it's back to what happened last season.
