Editor's note: ESPN.com’s Summer Shootaround series catches up on the offseason storylines for each conference. For more on the Pac-12, click here.
1. UCLA's late recruiting surge: Less than two months after a Sports Illustrated story threatened to damage the reputation of coach Ben Howland and his program, the Bruins added a pair of standout freshmen who could make UCLA a top-10 staple this season. Shooting guard Shabazz Muhammad -- the No. 2-ranked prospect in the class of 2012 -- announced his intentions during a live telecast on ESPNU in May. Center Tony Parker, who is ranked No. 26, followed suit soon after. Mix in fifth-ranked Kyle Anderson, a small forward who signed in the fall, and it's easy to see why UCLA's haul was ranked No. 1 in the country by ESPN.
2. Mark Lyons transfers to Arizona: The Wildcats' list of newcomers became even more impressive with the addition Lyons, who scored nearly 1,200 points in three seasons at Xavier. Arizona coach Sean Miller signed Lyons when he coached the Musketeers and had a chance to reconnect with him when Lyons decided to transfer for his final season. Lyons will provide a huge boost to a squad that also welcomes the country's third-ranked recruiting class. Mix in returnees such as Solomon Hill and Nick Johnson and there will be no excuses for the Wildcats missing the NCAA tournament, which they've done two of the past three seasons.
3. USC's bounce back: Could a team that finished 6-26 overall and 1-17 in Pac-12 play last season actually make the NCAA tournament in 2013? Trojans coach Kevin O'Neill says yes, and there appears to be validity to his optimism. Last year's squad lost four starters to season-ending injuries and was down to six scholarship players by the end of the season. Now USC is preparing to welcome back team captain Jio Fontan and NBA prospect Dewayne Dedmon along with newcomers such as Wake Forest transfers J.T. Terrell and Ari Stewart. Tissue-thin a year ago, the 2012-13 Trojans will be the deepest team of O'Neill's tenure.
4. Washington hurt by NBA draft: The Huskies' chances of repeating as Pac-12 champions took a major hit when sophomore small forward Terrence Ross and freshman point guard Tony Wroten left school early to turn pro. Both players became instant millionaires when they were selected in the first round. Ross was picked eighth by Toronto; Memphis nabbed Wroten with the 25th selection. The early departures will put additional pressure on players such as C.J. Wilcox, Abdul Gaddy and Aziz N'Diaye. Even with Ross and Wroten in the lineup, Washington missed the NCAA tournament last spring. Can they make it this season without them?
5. Can Jahii Carson make Arizona State relevant again?: The Sun Devils experienced their worst season under Herb Sendek when they went 10-21 last season. But let's face it: Arizona State hasn't had a quality point guard since Derek Glasser graduated two years ago. Carson was supposed to fill that void as a freshman last season, but he was ruled academically ineligible and never played a game. Luckily, he was able to practice with his teammates, which should help him adapt to the college game more quickly when he takes the court for the first time this fall. Arizona State has missed the NCAA tournament the past three seasons.
