I guess my point was that I think McIntosh might be ISU's most important player because of the mismatch he creates, for lots of teams including outside the Valley. Lee is clearly very good and advanced stats even favor him which I usually like a lot, but he isn't creating a mismatch. He might be too good for your best defender, but it isn't because of some significant size or athleticism advantage that you had no chance to overcome. Some teams have guys that can match up OK with McIntosh. Not many have guys that can match up with McIntosh and Hawkins at the same time. Which creates problems teams have to scheme against.
Lee shooting the cover off the ball is helping him a lot this year. He still turns the ball over a lot for a true PG for my taste, but ISU is more of a high-risk high-reward oriented team anyway.
