As recently as early last year, Beaulieu was playing pond hockey on defence. He didn`t know when to pinch and his d zone coverage was terrible. Then he got put with Sauve and started to catch on. For the first few games last year, he was behind Despres, Sauve, Gagne and Durepos on the depth chart. When things started to click he went from at best a 5th D to suddenly looking like a top 4 in a hurry. He started making better decisions on when to pinch and his in zone coverage improved immensely (playing with a vet can never hurt). Early this year, when Despres was away, Nate stuggled again (being asked to be a #1 D). When Despres returned, Nate`s game went back up (not having to lead the D). At the end of the year, Saint John was trying to rest Simon, and Nate brought his game up to a #1 D calibre, allowing Saint John to even give Simon 3rd pairing minutes in the playoffs.
Saint John went out and got Eric Gelinas at the deadline. Gelinas is signed by Jersey, but is clearly our #3 D, behind Despres and Beaulieu, despite Beaulieu being a year younger.
His weaknesses are things he has been improving drastically over the past year and a bit, which is why scouts have him so high.
