Over the last two weeks we’ve been taking a look at some players who had big springs for their respective teams. Some are upperclassmen finally coming into their own, some are younger guys taking advantage of open spots on the depth chart, while others are leap frogging some older players and making a name for themselves. Regardless, there were plenty of impressive performances in the Pac-12 this spring. All of these players are going to play a big part for their teams this fall, but which player do you think will be the most crucial to his team’s success in 2014? Rank them 1-12 here.

Here’s a breakdown of the players we’ve profiled over the past two weeks:

Arizona: WR Cayleb Jones -- The Wildcats might have the deepest wide receiver group in the entire conference, but could a Texas transfer become the most important one of the bunch? With a year spent studying the offense and learning from the sideline, Jones could be a major factor.

Arizona State: LB D.J. Calhoun -- The early enrollee ended the spring listed as a starter with Antonio Longino at the weakside linebacker position. With the Sun Devils trying to replace three starting linebackers, could Calhoun become a significant contributor as a true freshman? Seems likely.

Cal: RB Daniel Lasco -- Lasco found himself taking some extra reps this spring as Khalfani Muhammad (last season’s leading rusher) split time between the Cal track and football teams this spring. During his career he has been slowed by injury, but now that he’s finally healthy and taking more reps, could he battle Muhammad for the lead spot this fall?

Colorado: WR Bryce Bobo -- Colorado fans should feel encouraged by Bobo’s spring game performance (five catches, 132 yards) as they head into the summer wondering who can replace Paul Richardson's yardage. It’s highly unlikely that it’ll be one single player, but could Bobo carry a large part of it?

Oregon: WR Devon Allen -- When he wasn’t running for the Oregon track team this spring he was running circles around some Ducks defensive backs. The redshirt freshman could prove to be a huge player for Oregon as they look to replace last season’s top-three receivers as well as injured Bralon Addison’s production.

Oregon State: WR Victor Bolden -- Could Bolden be a possible replacement for some of the yardage lost by Biletnikoff Award winner Brandin Cooks? He has seen most of his time on special teams, but could step up as a big contributor in the fall as QB Sean Mannion looks to have another very big season for the Beavers.

Stanford: DL Aziz Shittu -- The sophomore, who can play every spot on the defensive line for the Cardinal, has received high praise this spring. Coach David Shaw said Shittu was, “probably the player of spring for us.” If it’s good enough for Shaw, is that good enough for you?

UCLA: CB Fabian Moreau -- He was a big contributor to the Bruins last season but during this spring season Moreau became a better leader for UCLA. Coach Jim Mora has given Moreau high praise and if the Bruins are able to take the South Division title next season, a bit part could be because of the breakout year Moreau could have.

USC: WR Nelson Agholor -- Chances are if you’re a USC fan, you know who Agholor is. If you’re not -- then he was the guy who played opposite Marqise Lee. But this spring Agholor took the steps to go from good WR to great WR, and next fall, the fruits of his labor could be on display for the entire conference to see.

Utah: RB Devontae Booker -- Booker is right on the heels of RB Bubba Poole, as displayed by his spring game performance (2 touchdowns, 19 carries, 103 yards). But between Booker, Poole and Troy McCormick, the Utes could have a three-headed monster at running back that Pac-12 teams would not enjoy having to face.

Washington: LB/RB Shaq Thompson -- He was the second-leading tackler for the Huskies last season so it wasn’t a defensive breakout spring for him. But considering he started getting offensive reps, it was a breakout spring for him as a running back. UW needs to replace Bishop Sankey’s yardage, could Thompson’s spring give him a jump start to do so?

Washington State: WR Vince Mayle -- The converted running back had a big spring for the Cougars. This spring Mayle got close to becoming quarterback Connor Halliday’s safety net. Considering Halliday threw for more than 4,500 yards last season, being his safety net would mean major, major yardage next fall.
