SI's Michael Farber has a good list of the "Five under-the-radar people who make a big impact" in the NHL. Three of the five have impacts on prospects. If you haven't heard of them before, you should definitely read up.
1. Hakan Andersson - Detroit Red Wings director of European scouting. People like to debate this one. Is his hit rate really that high, or do the Wings just take a lot of Europeans?
2. Chris Kelly -- Ottawa Senators forward
3. Benoit Allaire - NY Rangers goaltending coach.
4. Cory Murphy -- Florida Panther defenseman whom Tobias Enstrom really likes.
5. Trevor Timmins - Montreal Canadiens director of player recruitment and development. Farber calls him "anonymous" but he's actually out and about and quoted quite a bit.
