I wouldn't say he's completely fallen off as a prospect. He's always been very raw, but the potential is still there. Moving to BC will definitely do him good. I'd say he wasn't truly a potential top 10 prospect even two years ago but because of his size, many got carried away.
The NTDP has not been very consistent in recent years. In some years, players have made big strides and sometimes the development has not been as desired. It feels like it has been very much up to the team. 2007s was not a good team and it felt like it froze everyone's development as well. That's a big difference to 2006s, for example.
This may push some players to the CHL, which is obviously not what USA Hockey wants. The 2009s are a really important age group for the future of the NTDP. Also when it comes to duals.
