Four caveats to keep in mind as you digest our projections for Matt Leinart's first professional football contract:
1. The signing bonus, of course, is the only guaranteed portion of the contract.
2. Total contracts of different players cannot be compared, not only because they sign for varying numbers of years, but more importantly because very few contracts stay in place through the length of their term.
3. Bonuses are arbitrary. We've used information from previous years to try to determine standard increases, but agents exist to create wiggle room.
4. The percentage of increases that have become standard over the years might not apply this year. Teams could be more reluctant to give more guaranteed money as a result of uncertainty over the terms of the next collective bargaining agreement. The current CBA expires at the end of this season.
