With college football spring camps gradually opening across the country, which storylines warrant your undivided attention? Here are the 10 that’ll make the biggest impact.

Every campus will serve as the stage for angles this March and April. There will be no shortage of riveting storylines that sometimes spawn as many questions as answers while spring practice unfolds. Each of the 128 FBS programs will generate headlines, from the breakout star to the broken body part that derails a season before it ever gets off the ground.

However, the following subplots will be more than just compelling and entertaining over the next eight weeks. Their outcomes, beginning today and likely concluding at some point during the dog days of summer, could impact races for conference crowns and playoff berths.

10. Year of the Volunteer?

Long-suffering Tennessee fans have grown accustomed to mediocrity. Too accustomed. But Butch Jones has enough momentum and returning talent to take the next step after going 9-4 a year ago.

That the Vols haven’t won an SEC title this century has been well-documented. However, Tennessee has a little wind at its back, coming off its best year since 2007. Also, a slew of starters on both sides of the ball return from Jones’ third team in Knoxville. The hunt for an East Division crown—at the very least—began on March 7 for during the start of spring camp – but football isn’t quite the No. 1 topic with controversy swirling around Butch Jones and the program.

9. Turning the Corner in L.A.

Either Oregon or Stanford has won the last seven Pac-12 titles. USC and UCLA feel that this might finally be the year that the hardware returns to Los Angeles.

The Trojans and the Bruins are trending upward in terms of talent acquisition, but neither program has been able to close the deal for reasons ranging from injuries and youth to NCAA probation. There’s hope, though, that expectations can be met in 2016.

At UCLA, Jim Mora is beginning his fifth season, QB Josh Rosen is no longer green and the team can’t possibly be as injury-prone as it was last year. Across town, USC believes it finally has sideline stability in Clay Helton to go along a deepening roster.

8. Retooling Baylor Lines

Line play is rarely top of mind when the discussion is Baylor. However, it will be when the Bears practice throughout March.

If Baylor is going to shake off last season’s deflating finish, fumbling a chance at a playoff berth, it’ll have to fix both lines, beginning this month. The Bears were ransacked by graduation and nose tackle Andrew Billings’ early departure, leaving a single starter, center Kyle Fuller, behind. While Baylor will keep scoring by the bushel as long as Art Briles is in Waco, there’s a hard cap on the program’s 2016 ceiling if line play becomes a liability when Big 12 play begins.

7. Brandon Harris’ Maturation

Few individuals will be more closely tied to their program’s up-or-down trajectory than Brandon Harris.

LSU is little more than competent quarterback play away from being a serious contender for an SEC crown—and more. For a twist, the Tigers weren’t hammered by early entries to the NFL Draft. Nine starters return to each side of the ball, and head coach Les Miles and running back Leonard Fournette will operate with a sense of urgency and purpose in 2016. Still, Harris and the passing game must emerge from the one-dimensional graveyard, because it’s tough to travel too far these days with a feeble and unimaginative attack.

6. Rumble in South Bend

There’s nothing like a heated quarterback competition to warm up the chilly spring months. And no quarterback derby will be more compelling than the one between Notre Dame’s DeShone Kizer and Malik Zaire.

The 2015 Irish team belonged to Zaire, so much so that Everett Golson packed his bags for Tallahassee. Zaire, though, suffered a season-ending ankle fracture in Week 2. Enter Kizer who set out to create a quarterback controversy by performing like a future first-round draft choice. Both players can run Brian Kelly’s offense at a high level, which means this battle will last until the summer, and could conjure up transfer chatter for a second straight year.

5. How Will Jim Harbaugh Top Himself?

For better or worse these days, when Harbaugh sneezes, the entire college football ecosystem catches the flu. Or a case of mild insanity.

Harbaugh is deeply rooted at the center of the coaching universe, part by design to attract incessant media attention in some Trumpian fashion. Everything—literally—that the coach does and says is going to be reported, discussed and shoved through the channels of hyper scrutiny. And with so many paying such close attention to Harbaugh, you can bank on him seizing the opportunity to breed splashy headlines that keep the Wolverines front and center nationally.

4. Bama Backfield

The Tide will be fine, because Nick Saban and perennial killer recruiting classes ensure it. Still, there’ll be some tinkering to do on offense, especially in the backfield.

Alabama will enter 2016 with a new starting quarterback for a third year in a row and a need to replace a pair of next-level backs, Derrick Henry and Kenyan Drake. Bo Scarbrough and Damien Harris will vie until April 16 to be Saban’s next running game collaboration, each hoping to be the feature back.
