IIRC, that's correct. BM graduated high school at the end of SM's freshman year in high school. That means he had already spent a year playing for and had been cut from the Toronto farm team by the time he dated SM. And he'd worked a couple years beyond that.
So, this guy who'd been out of high school for a few years, had already played and then lost his place on a farm team, and who was now a full time employee making a living targeted for his "affections" a girl who was still in high school, living with her mother who was recently divorced from her father, and who was suffering from cancer. This is NOT a high school romance of two equal in agency they exercise over their own lives.
BM knew where to look to find someone who might - at that phase and with those circumstances in her life - be inclined to be submissive, to mistake "possessiveness" for "protection," and to mistake "control" for "authority."
IMO, one might say that he looks in similar circumstances - weakened, and in need with few options available to them - for his "contractors" who he so readily pointed the finger at (CC) or dismissed as non-reliable witnesses (JP, MG) when LE appeared to pointing the finger at him.
