With Colorado's training camp in full swing, a number of questions marks remain. Here are three position battles Pac-12 fans will want to monitor:
Quarterback: Connor Wood vs. Nick Hirschman vs. Jordan Webb
Wood, a sophomore, took most of the snaps in spring ball but that was by default because his classmate, Hirschman, had a broken bone in his foot. Hirschman has a little more experience but enjoyed nominal success. He completed 18 of 35 attempts for 192 yards last season. Intriguing Kansas transfer Jordan Webb, a junior, joined the club this summer, making this a three-horse race. Webb completed 179 of 281 passes last season (63.7 percent) for 1,884 yards with 13 TDs and 12 INTs.
Cornerback: Josh Moten vs. Jered Bell
Moten, who was suspended part of last season for violating team rules, had a strong spring. He has good speed, loose hips and saw action in five games last year. Ideally, coach Jon Embree would like him to step up and take reins, but Bell, his fellow sophomore, will bear watching. He appeared to be challenging for a starting job when he tore his ACL last August. He's 6-feet tall and has beefed up to 195 pounds, matching Moten's ability to hang with the conference's bigger receivers.
Defensive tackle: Kirk Poston vs. Eric Richter vs. Justin Solis vs. Josh Tupou vs. ?
This is a big area of concern on the roster. Poston was listed as a starter alongside Will Pericak, but he only weighs 250 pounds. That won't get it done. Richter (310) is the biggest and strongest member of this quartet. He's also a senior but he has to grasp the mental aspects of the game better than he has. Solis and Tupou are highly regarded recruits who would do wonders for this unit with quick progression. Injury-prone Nate Bonsu and John Tuso could also be factors.
