Over the next two weeks, we'll be examining the strongest and weakest positions on each Big 12 team heading into summer workouts and preseason camp.
We continue the series with the Oklahoma Sooners:
Strongest position: Quarterback
Baker Mayfield has 27 career wins as a starting quarterback, the most of any returner in the country. He also already owns the FBS season passing efficiency record. And he has a chance to join Herschel Walker as the only other player since the 1940s to finish in the top four of the Heisman voting three times.
Mayfield, however, isn't the only reason Oklahoma might boast the best collection of quarterbacks in the country.
Previously a five-star recruit, Kyler Murray was the star of OU's spring game, tossing a 70-yard touchdown to Jeffrey Mead. Murray is battling former ESPN 300 quarterback prospect Austin Kendall for the backup job -- a battle that will spill over into 2018 for the right to succeed Mayfield.
This is a terrific group with a star in Mayfield and a pair of promising players behind him.
Weakest position: Wide receiver
Though this unit continues to look better and better, it remains arguably the biggest question mark on the team.
The Sooners addressed the departure of Heisman finalist Dede Westbrook by landing one of the high profile grad transfers this offseason in Jeff Badet. The former Kentucky standout led the SEC last year in yards per catch.
Badet, however, won't be the only speedy newcomer to Mayfield's receiving corps.
ESPN JC 50 standout Marquise Brown joined the Sooners before spring ball. He showed up weighing just 144 pounds, but displayed tantalizing speed.
The continued emergence of Mead was a welcome development for the Sooners over the spring, as well. At 6-foot-5, he complements the diminutive Brown and Badet as a big-play option for Mayfield on the outside.
Throw in All-Big 12 tight end Mark Andrews, and this has the chance to be a stronger group than expected.
Of course, it still has to come together. And with so many new pieces, that remains to be seen.
