With Caleb Williams' transfer to USC official, the future looks good for Lincoln Riley, Trojans. But great?

On Tuesday, Caleb Williams announced (finally — what was the hold up anyway?) he's transferring to USC. He's just the latest current or future Sooner to announce he's joining Lincoln Riley in Los Angeles, but Williams is clearly the most important. Quarterbacks with supreme talent are always most important.

Now that USC has its quarterback, what are we to make of the Trojans' future?

Berry: Well, the addition of Williams will expedite Riley's rebuilding, no doubt. And the transfer portal potentially speeds up any rebuilding job. But despite Southern Cal's newcomers, it's not likely the Trojans turn around overnight. USC is 22-21 over the last four seasons. The Trojans have some holdover ballplayers, but not near enough of what Riley needs.

Jenni: There's evidence of that. While I don't pretend to know the state of USC football, folks in Los Angeles surely understand the lay of the LaLa land. And there's a strong sentiment that USC is still behind UCLA. Now, that can change quickly once the games start. But even in the doughy-soft Pac-12, you need a well of players. Not saying USC's is dry, but it may be even shallower than a lot of us would think.

Berry: But the Pac-12 is there for the taking. Or at least there for contention. Oregon and Utah are consistent winners. Otherwise, the conference is a bunch of up-and-downers. Including UCLA. Stanford, Arizona State, Washington. This isn't like USC has a bunch of programs to jump over. Just playing solid football gets USC to third in the Pac-12. From there, anything's possible.

Jenni: Frankly, Williams is the kind of dynamic talent that could be the difference in several games against Pac-12 competition. OU fans might not like to be reminded of it right now, but he is special. And because of the Pac-12 is so ripe for picking, he could single handedly be the difference in two, three, four or even more games for USC. But here's the thing: Sooners everywhere know offense can only get you so far. Just ask Baker Mayfield, Kyler Murray and Jalen Hurts. Still, what seems possible for USC next season? Could it win 10 games?

Berry: COULD it? Sure. We saw teams like Pitt and Michigan State rise up and get in that neighborhood last season. Michigan State, in particular, used the portal to stage an uprising. But 10 is a tall order. USC's non-conference schedule is Rice, Fresno State and Notre Dame. All at the LA Coliseum, but still. Fresno State went 10-3 last season and Notre Dame is Notre Dame. But the Trojans don't play Oregon, so the Pac-12 schedule is somewhat manageable.

Jenni: Eight wins seems doable, though I suspect USC fans want way more. I have no doubt Riley will be successful — he's a good coach, USC is a traditional blueblood and the Pac-12 is down — but even with Williams on the roster, it will take some time. After all, Williams just calls himself Superman. He doesn't actually have super powers.
