Hill’s last one was the season opener at UConn (308 yards in 2014), and he only played five games that year. Hill has had three games of 300 yards-plus passing in his frequently interrupted, injury-plagued career of just 33 games.

This season, BYU’s pass game totals have been 202 at Arizona, 185 (Utah), 250 (UCLA), 241 (West Virginia), 248 (Toledo), 138 (Michigan State), 165 (Mississippi State) and 187 against Boise State. Still, Mangum’s season yards per game average was 259.

That 2015 Mangum team then passed for 309 against Boise State, 365 (UConn), 341 (East Carolina), 411 (Wagner), 362 (Fresno State) and 315 against Utah. Tanner Mangum then came in and passed for 111, 42 of it coming on the Hail Mary pass to Mitch Mathews on the game-winning play. Taysom Hill got 268 yards or 71 percent of that before leaving the game with a season-ending injury. Last year, BYU passed for 379 in the opener at Nebraska. It has been an expectation right up there with candy at the end of October and turkey in November. Still, over time, BYU quarterbacks have regularly got to 300, a rite of passage. It was an era when defenses didn’t have the NFL influences of today. But it is a tradition, a storied convention sewn by BYU quarterbacks back in the WAC days when UTEP, New Mexico and Utah were cross-eyed defenses incapable of stopping it. McMahon set the national mark for a career with 17. Twice, Detmer had twelve 300-yard passing games in a season, another NCAA mark. He got 24 of them in a row, an NCAA record. That lasted a decade when no other college passer could top it.

Jim McMahon set an NCAA record by collecting 12 of them in consecutive games. The 300-yard figure is kind of sacred in BYU football history. The last time BYU had a 300-yard passing game was in the Las Vegas Bowl, Dec. Where have all BYU’s 300-yard passing games gone?
