Bronco didn't do a terrible job recruiting the O-Line at first....especially with Crowton's recruits.
But the O-Line issues hit hard when Sitake was hired. Bronco even knew it was a huge problem and had to resort to getting transfers from SUU. He hired 2J because Weber was so terrible.
Remember... It takes sometimes between 2-3 years for an OLine recruit to report to BYU after high school.
