Just a thought on market dynamics.
Apart from the rookie 1st rounder money, HT got a second contract worth of 4y/40 Mi if i'm not mistaken.
Looking at the money spent on huge impact players not only now but at his time too, he certainly deserved a lot more, but he got a bad market on his contract year, had talks with the Jets and Steelers only and then came back to the Pats.
Even though this is a super inflated market sometimes it has correlation with how a normal market works, I find that interesting.
