She has. 3 games against P5 schools: Iowa, Rutgers and Michigan. Michigan was the only ranked team, and was somewhere around 20.
5 pts vs Iowa (1-8 from the floor, 1-6 from 3)
4 pts vs. RU (2-9 from the floor, 0-5 from 3)
14 pts vs Michigan (5-21 from the floor, 1-8 from 3)
This comes out to 7.6 ppg shooting 21% from the floor (8-38) and 11% from 3 (2-19). That's compared to her season average last year of 16 ppg, 38.5% from the floor and 31.7% from deep.
Jordan did not show she can play against high level competition at WMU, and that competition will pale in comparison to what she plays against in the SEC (and (OOC against UConn). That's why I'm not sold on her until she shows that she can be a factor against better teams.
