But his 3P% fell off his sophomore year, prior to the back surgery.
Prior to his first game, he had to have foot surgery over the summer. He came into his freshman season shooting .357 with the line at 20' 9". That year he suffered a hip injury, and he had surgery to repair a torn labrum and sports hernia in the off-season.
As a sophomore, he shot .280 with the line pushed back to 22' 1.75". In the offseason, he slipped two discs in his back and had to have surgery.
As a junior, he missed the first 11 games of the season, and came back shooting .204 for the remainder of the year.
As a senior, he shot .271 after his first healthy offseason, which was more in line with his sophomore year shooting at the current 3pt-line distance prior to his back injury. In the subsequent offseason, he suffered a knee injury.
As a 5th year, he missed the first 3 games still rehabbing his knee, and came back to shoot .203

His one good season from range was with an arc that was 15.75" closer than it was his next four years. One or two steps inside the line, he still had a good mid-range shot - but those "toe the line" threes as a freshman were only worth 2 points the rest of his college career.
The NBA line is even further back at 23' 9", another 19" farther than the NCAA line. It would be difficult for McConnell to suddenly start hitting consistently at that distance.
