No he wasn't. Read the actual reports from the NCAA on both cases. Cal wasn't going around arranging for Derrick Rose to take fake SATs. The NCAA already cleared him anyway before backtracking on it. If Cal was as guilty as you say he would have gotten a show cause just like Pearl did after he left Tennessee.
UK didn't recruit the vast majority of the talent Cal got here. Cal's history with getting players to the NBA did, that just coincided closely to when he arrived here. He was already known as the coach that got point guards in the NBA after a year with Rose and Evans, and Wall would have strengthened that reputation regardless of where Cal was coaching. If you think any of Wall, Bledsoe, Knight, Teague, or the Harrisons came here for UK and not Cal you're mistaken. Wall was already committed to Memphis and Bledsoe had ruled us out long before Cal was hired here.
