Hazell added Panfil, Yancey, Clark, and a handful of other 3-star guys. That may have actually been the pinnacle of his recruiting at Purdue. Things went downhill from there, and what should have been an improved class in 2014 with DH2 having an entire recruiting cycle to work with, actually took a step backwards..
Panfil was recruited and visited before Hazell came and was given credit to be recruited by assistants.
Yancey was a flip from Kentucky and didn't sign until January. Credit was given to Shoop for his recruitment, so you could make the argument that he was signed by Hazell, but he was already being heavily recruited.
Clark signed in December so Hazell didn't sign him.
