No he didn’t. Kyle McCord threw for nearly 100 more yards per game last year. He never led the country in passing yards per game, and last year wasn’t his good year. The only thing he led the country in was interceptions.
I do wonder how his initial recruitment from the portal went though. I wonder if he had other decent options but went to UCLA because they had a need and were close to home, rather than no better program giving him a shot. Then when he transferred again he got to upgrade. In any case, we are fortunate that the Iamacoachkilla family did what they did.
