Spring game Saturday: How to watch, updates

College football’s biggest day of the spring is Saturday as 48 FBS programs will take the field for spring games or open practices.

Among those 48 programs hosting spring games are a number of the nation’s top programs. Spring games offer us the first glimpse at these teams ahead of the season, and while you don’t want to put too much stock in what happens in a scrimmage, there are some things we can learn.

Here are the storylines to watch for some of the top teams in action on Saturday — surprise, there are lots of quarterback questions! — as well as how you can watch each of their games (all times Eastern).

CBS Sports will update this post throughout the day with results and takeaways as these spring games come to their respective conclusions.

Notre Dame — 12:30 p.m., NBCSN: All eyes will be on the quarterback battle between DeShone Kizer and Malik Zaire. Our Chip Patterson broke down said QB battle earlier this week if you want a deeper dive into what to look for between those two on Saturday.

Ohio State — 1:30 p.m., Big Ten Network: The Buckeyes saw a ton of talent leave this year for the NFL and those departures will be a big test of Ohio State’s roster depth. Urban Meyer can recruit as well as anyone and the Buckeyes have talent, but losing top guys from most every position group — OL, DL, RB, WR, DB, LB — will make for Meyer’s toughest task yet at Ohio State. The good news is that J.T. Barrett is still in Columbus, which should help ease the transition for other new offensive starters, but there are position battles still to be decided on both sides of the ball.

Miami — 2 p.m., ESPN3: Saturday is the (public) opening of the Mark Richt era at Miami. He has a quality quarterback in Brad Kaaya and a lot of returning talent on both sides of the ball, which has optimism for 2016 as high as it’s been in Coral Gables in a long time. What will the team look like on the field under Richt? We’ll get a glimpse of that on Saturday.

Tennessee — 2 p.m., SEC Network: How will Tennessee handle being the SEC East frontrunner? The rebuild is over and it’s time for Butch Jones and the Vols to put it all together for a division championship in 2016.

Texas — 2 p.m., Longhorn Network: Charlie Strong’s seat is quite warm and Texas expects results to improve in his third year. The problem? The Longhorns still aren’t sure if they have a quarterback. We’ll find out if Tyrone Swoopes or anyone else has truly taken the job by the, pardon the pun, horns on Saturday.

Alabama — 3:00 p.m., ESPN: Guess what? Alabama’s going to be really good again this year. The Tide aren’t sure who will be the quarterback at the start of the season, but that hasn’t bothered them the past two years. Getting to check in on the QB battle will be nice, but what is most exciting is the chance to see running back Bo Scarbrough. He gets spoken of like a mythical creature with his scrimmage numbers and we will finally get a chance to see him on full display on Saturday. Oh yeah, and the defense is still filthy.

Georgia — 4 p.m., ESPNU: Kirby Smart has already begun the Alabama-fication of Georgia’s football program. On Saturday, we’ll see what changes are being made on the field. Smart’s area of expertise is on the defensive side of the ball, where Georgia should be strong once again, but the offense is where the Bulldogs must improve from a year ago. The quarterback battle between Greyson Lambert, Brice Ramsey and Jacob Eason is the main event, but the overall offensive scheme changes will be something to keep an eye on with the new coaching staff in place.

LSU — 4 p.m., SEC Network: Leonard Fournette is back, which is fun and every time we get to see him do things on the football field it’s a treat, but eyes will be focused on the man in front of him in the LSU backfield. Quarterback has been a weakness for two years in Baton Rouge, but there’s optimism that Brandon Harris will build on last year’s close to the season and be a net positive from under center this year. If he can be a consistent, accurate passer then LSU can take a step forward this year.

USC — 6 p.m., Pac-12 Network: This will be Clay Helton’s first time running a spring practice as the Trojans make the transition to Helton as the full-time coach. There are new coordinators on both sides of the ball — although newly promoted offensive coordinator Tee Martin has been on staff for years — and quarterback Cody Kessler is gone so Max Browne and Sam Darnold are vying for the opportunity to start for the Trojans.
