Why do you think that? What has Beecher done at 17 that Frederic didn't? Beecher had 43 points in 63 games for the USDP, Frederic had 40 in 61. Beecher scored 4 points at the U-18's, Frederic had 7 points in the same tourney. They both played bottom6 roles.
As an 18 year old freshman, Frederic was a point per game players in college, he followed that up with another ppg season and being named assistant captain as as sophomore. All in, he scored 32 goals in his two years in college. He also scored 5 goals in 7 games at the WJC's that year.
IMO, it's way too early to say one will be better than the other. Frederic's post draft years have been very solid, the kind of production that projects to a top6 forward, and I'd be delighted if Beecher continues to mirror him.
It seems like everyone is down on Frederic because he didn't light up Providence his first year. That's a mistake IMO. First off, he did score at a 21 goal pace in the first half of his first pro season. That's not nothing. Marchand only had 18 goals as a rookie in the AHL. Frederic's points per game were the same pace as Kuhlman who's 3 years older. Also, a lot of first year pros do most of their damage in the second half. Sticking with Kuhlman as an example, he only had 9 points in his first 30 AHL games, then he put up 21 points in his last 28 games.
I don't mean to pick on you but it seems like a lot of folks are writing him off. Even that writer in the other thread had him as the 4th line center 5 years from now.
