No. 1 -- The QBs. Jeff Tuel is the presumptive starter at this point, but was a bit off during WSU's last scrimmage, completing just 22 of 47 passes. This will be a chance for him to end the spring on a high note. Same with backup David Gilbertson. No. 2 -- Who separates at WR? This position is the deepest on WSU's offense, but who will see the most time in the spring game? That could tell us something about what the rotation might be. Star WR Marquess Wilson has been singled out by coach Mike Leach as needing a better work ethic. He can prove he's improved with a solid performance. No. 3 -- LB depth. The Cougars will likely be without starters Darryl Monroe and Chester Su'a, meaning backups Darren Markle and Corey Laufasa could see plenty of reps with the starting unit.
