Bowers' deal guaranteed for two years

The Tampa Bay Buccaneers have some protection in case those concerns about Da'Quan Bowers' knee turn out to be real.

According to documents obtained by ESPN.com, only the first two years of Bowers’ contract are guaranteed. That’s pretty much the norm for second-round draft picks. Most first-round picks have deals that are guaranteed for four years.

Bowers initially was viewed as a potential top-10 overall pick, but tumbled to the second round due to his surgically repaired knee. The Bucs took him at No. 51 overall and the total value of his four-year deal is $3,855,636, and his average per year is $963,909. They paid him a $1,304,100 signing bonus. His 2011 salary will be $375,000. In 2012, it jumps to $550,256. Bowers’ base salary rises to $725,512 in 2013 and $900,768 in 2014.
