1. Toon time -- After struggling at receiver in 2008, Wisconsin might have identified a top wideout this spring, and he has a familiar name. Sophomore Nick Toon, the son of former Wisconsin great and three-time All-Pro Al Toon, blossomed during spring ball. Toon brings both speed and size to the outside receiver spot. He had a game-high four receptions for 62 yards and a touchdown in the spring game.
2. Phillips emerges -- Wisconsin wanted to find another quarterback to challenge projected starter Dustin Sherer, and redshirt freshman Curt Phillips emerged late in spring ball. Phillips finished with a flourish, completing 10 of 16 passes for 122 yards and two touchdowns in the spring game. The Tennessee native might not be a textbook passer, but he brings playmaking ability to the pocket.
3. High Wattage -- Opportunity abounds on the defensive line, which loses three multiyear starters, and end J.J. Watt seized it this spring. The Central Michigan transfer earned a starting spot opposite O'Brien Schofield and has the versatility to play both line positions after transforming his body during the last year. Watt's presence elevates expectations for the Badgers' pass rush.
1. Quarterback clarity -- The big dilemma in Madison is this: Will Wisconsin go with a more experienced player in Sherer and live with another one-and-done situation at quarterback, or will the coaches take a risk with Phillips? Sherer had a solid offseason and played well at points last season. He likely remains the team's best option, but Phillips could provide continuity for the future.
2. Secondary shuffle -- At least two starting defensive back positions and possibly three are unsettled entering the summer. Hard-hitting junior safety Jay Valai must fend off senior Aubrey Pleasant for a starting spot, while Niles Brinkley, last year's interceptions leader, is being pushed by sophomore Devin Smith. Senior Shane Carter is listed as a backup safety on the post-spring depth chart, but he could push Chris Maragos.
3. Clay's conditioning -- There's little doubt that sophomore John Clay possesses the skills to be a first-team All-Big Ten running back in 2009. But Clay has struggled with his weight, which exceeded 250 pounds late last season. He also has had recurrent ankle problems, so maintaining a healthy weight (235-240 pounds) will be vital through the summer and into preseason camp.
