What we learned in the Pac-12 this spring
1. Quarterback competitions (mostly) unresolved: Arizona, California, Colorado, Oregon State and USC entered spring with straight-up QB competitions, and none arrived at any clarity at the position, though some seemed to hint at a front-runner. B.J. Denker looked like the Wildcats' best healthy QB, while Cal's Zach Kline seemed to assert himself slightly for the Golden Bears. At Colorado, Connor Wood's case was helped by attrition. USC's and Oregon State's battles were too close to call.
Further, returning veteran starters with something to prove, including Washington's Keith Price, Washington State's Connor Halliday and Utah's Travis Wilson seemed to assert themselves to varying degrees, though Austin Apodaca could push Halliday in the fall.
2. New coaches, new ways: Sonny Dykes took over at California as did Mike MacIntyre at Colorado. Both, as could be expected, brought changes. Mark Helfrich replaced Chip Kelly at Oregon and, as could be expected, he changed almost nothing. The most obvious change at Cal was open practice, which former coach Jeff Tedford's abandonment of curiously coincided with the Bears gradual decline. The Bears will adopt a no-huddle, spread offense, replacing Tedford's pro-style scheme, and switch from a 3-4 to a 4-3 defense, a reverse of the overall Pac-12 trend. MacIntyre arrived preaching relentless optimism and a pistol offense, while defensive coordinator Kent Baer will retain a 4-3 scheme, but hopefully get better results with his version.
3. Defense, line play look strong: The Pac-12 heads into 2013 poised for a banner year. Oregon and Stanford look like national title contenders -- both are likely preseason top-five teams -- while as many as seven conference teams seem like top-25 candidates. Some of the reasons for the promise are typical: returning QBs and skill players. But what's potentially a bigger reason for improved national standing is the physical side of the game: Offensive line and defense. Nine teams have at least seven starters coming back on defense, while seven teams welcome back four starters on the offensive line. Only one team, Utah, doesn't have at least three starters back on the O-line. Further, there's as much, if not more, star power coming back on the lines and on defense than at the skill positions.
