1. Quarterback options -- The Spartans' quarterback competition is far from over, and that's not a bad thing. Sophomores Kirk Cousins and Keith Nichol both performed well this spring and put up the exact same totals (357 pass yards, 4 TDs) in the Green-White game. The coaches are comfortable with either player, and both quarterbacks have the athleticism that will allow the offense to expand.
2. Safety depth -- Several key contributors in the secondary missed spring ball with injuries, but the Spartans bolstered their depth at safety with Trenton Robinson. The redshirt freshman continually impressed head coach Mark Dantonio, who mentioned Robinson every time he met with reporters. Robinson could push for a starting spot alongside Danny Fortener or Kendell Davis-Clark.
3. High and tight -- The tight end spot might be phased out for many college teams, but not Michigan State. The Spartans could have more depth at tight end than any Big Ten team -- Wisconsin's right there, too -- as Clemson transfer Brian Linthicum joins Charlie Gantt and Garrett Celek.
1. Ringer's replacement -- Arguably no player in the Big Ten did more for his team last fall than running back Javon Ringer, and Michigan State continues to look for a capable successor or two. None of the four candidates created much separation this spring, and incoming freshman Edwin Baker and Larry Caper will have opportunities to compete in preseason camp. Head coach Mark Dantonio wants to identify 2-3 reliable backs.
2. Offensive line -- Dantonio saw promising signs from a revamped line toward the end of the spring, but some doubt still remains. Junior J'Michael Deane and sophomore Jared McGaha must continue to develop on the right side of the line. Left tackle Rocco Cironi also returns from a shoulder injury and needs to re-establish himself.
3. Pass-rush help -- The Spartans finished eighth in the league in sacks last season (26) and need to identify a second pass-rusher to complement Trevor Anderson. The starting end spot opposite Anderson remains up for grabs, and redshirt freshman Tyler Hoover could land it after a solid spring. Colin Neely also is in the mix.
