That's a journeyman rate. Our highest paid lineman under contract is currently Morgan Moses, who will count $9.6 million against the cap in 2021. Roullier is next at about $5 million against the cap this year.
$5 million would put Williams at about the 20th highest paid LT in the league. I think that's probably where I'd value him these days. At his age he's not going to get a long-term backloaded deal.
If he is expecting more than that, I and I figure he is, let him get it somewhere else. Shrug.
