Yes, he's a RW, though he can play either wing.
The general consensus is that he'll play 1 more year at BC, then go pro, but that could change depending on what Smith and Leonard do. Gauthier is expected to leave. If Smith and Leonard leave, that could change Gabe's decision. BC has some good players coming in, notably James Hagens, who could be the 1st overall pick in 2025, so that could factor into his decision as well.
Also, how they do in the NCAA tournament this year could impact all of their decisions. If they don't win it this year, all of Smith, Leonard and Perreault might decide to stay another year and try to win a championship. If they do win, maybe none of them go back.
I expect that if he returns to BC next year, that will be it for him, and he'll sign with the Rangers immediately following the season.
