I agree; for a starting LT with 2 pro bowls on his resume, $8M per year is reasonable. Beatty just signed a $7.5M per year contract, so it sounds like Bushrod is base lining that deal. However, I don't think Bushrod will get that on the open market.
$8M is where his camp will start negotiations (assuming the original poster is accurate), it will be too rich for our taste, and he will test the market. Much like Jake Long he will be welcomed to a lukewarm tackle market and realize that he is worth $6M-$7M per year. I actually think we will offer him a deal similar to Beatty.
