In the 4 seasons that Leaky Black was a starter, our highest NCAA Tournament seed was #9 and two times we missed the NCAA Tournament. Those teams weren't all that good and part of it was because we had an extremely limited offensive player at the wing. Of course, there were several other factors, but Leaky was part of 4 somewhat limited teams.
I don't personally credit Leaky a ton for the 2022 run to the Finals. We made 13 3's against Marquette, 11 3's against Baylor, Caleb Love basically took over against UCLA, St. Peter's was a 15 seed. He made timely buckets against Duke though. During that 2022 run, I honestly think Leaky was the 5th most valuable player during that run.
Part of the 2022-23 disaster was because Leaky was so offensively limited on a roster that couldn't shoot the ball the entire season.
I don't think two #9 seeds in 4 full time starting seasons helps the Leaky argument much.
