Here's a breakdown of what each letter grade is worth financially.
A: $6+ million AAV (annual average value), 3+ years guaranteed money
B: $2-6 million AAV, 2 years or fewer guaranteed money
C: $2 million or less AAV, 2 years or fewer guaranteed money
D: Minimum salary, 1 year contract
I was a little surprised Polian had Bethea graded higher than Davis, and I was surprised Davis was also graded lower than McAfee and Brown.
One other noted free agent is offensive lineman Mike McGlynn. Polian gave McGlynn a D. He lost his starting job at guard momentarily but was still a better center than Samson Satele. This should help you put into perspective how low McGlynn graded out, receiver Darrius Heyward-Bey was given a C. Yes, Heyward-Bey, who went from starting the season as the Colts’ No. 2 receiver to ending the season on special teams, graded out higher than McGlynn.
