What Spring Practice will tell us about The Defensive Line

The defensive line and linebackers have their 2012 script pretty well set with maybe the only questions being amount of time either meaningful rotations or end of game mop up based on performance or injury.  Spring will give an opportunity for Kona Schwenke, Chase Houndshell and TonySpringman to step up and show their worth.  Spring will give us insight as to where and how Stephon Tuitt will be used.  Tuitt can play the nose or the end; he probably will play both significantly depending on the situation.  Spring may also shed light on whether or not Sheldon Day will preserve a year of eligibility or get the ball rolling early in his career.
