Right off the bat you start wanting to compare McLean with past UConn players. Do you? No. You compare McLean as a rising senior in HS to players you remember best as senior college AA's. I watched UConn when TWilliams was a freshman and same with GWilliams but I'm certain that I didn't see either before their senior years of HS.
If you insist on making comparisons then compare them at the same points in their careers. You also compare McLean as a HS junior with Barbara Turner as a college senior (I don't think Turner was ever a "freshman".

And Turner is nothing like what I have seen of McLean. Turner overcame her lack of physical biggness with mental bigness and incredible strength. McLean uses her leaping ability and quickness.
My personal feeling is that comparing new recruits with past players can be fun but it is unfair when everyone remembers Jefferson, Charles, G Williams et al at their best as seniors. They don't remember how they all struggled for their first 2 years. Even Stewart had a rough first season, confused at both ends of the court despite some brilliant moments. Then they compound it by comparing them to high school juniors.
Geno, when comparing Bueckers with Taurasi was reported as having told the Hopkins coach that she was ahead of Taurasi AT THE SAME POINT IN THEIR CAREERS. I wish more would do the same.
Of course this is just my opinion.
