I believe it belongs to SF Brian McCarl. www.whatifsports.com/hd/playerprofile/ratings.aspx?tid=0&pid=1608454
He arrived at Alabama as the #1 HS player with an 870 rating, rising to 1015 as a sophomore, and finishing as a 1038-rated senior. In that time, he led us to two National Titles, a Final Four, and a Sweet Sixteen (RPIs of 1, 1, 1, and 3), with a total record of 118-17. In the toughest conference in Smith, he was Player of the Year twice, Defensive Player of the Year once, and lost out on National Player of the Year twice only because a mildly successful mid-major gives one player a year all their shots and gets 35 ppg. He's Alabama's all-time leading scorer, and made Smith's all-time top scorers' list as well. His 15 ppg came against the #1 SoS all four seasons, and were scored in the flow of the game (rather than due to a crazily high distribution), as evidenced by his 52.7% career FG%. Had he played more than just to fairly fresh (23.7 mpg) and had I upped his distro as high as he could've handled it, he could easily have scored 22-24 ppg over his entire career, and added significantly to his 4.6 boards and nearly 2 assists, 1 steal and 1 block.
This combination of ratings, success, stats, and a willingness to stay all 4 years gives Brian the best D1 career I've seen and, I believe, the best one ever. Plus, he still rides the bus.
We'll miss you, Brian!
