I thought his contract was 100% guaranteed no matter what
$230M, with $160M guaranteed.
That guaranteed percentage (70%-75%) is what all the big-$ QB-contract extensions have been for years.
The exception was Deshaun Watson who had a no trade clause and said
'No thank you' to a trade to Cleveland before Browns' owner Jimmy Haslam said:
'What if I fully guarantee your contract'
... to which Watson replied:
'Cleveland sounds like a lovely place to play football'.
Then for two years, Lamar Jackson said:
'Cleveland re-set the market!'; and most Talking-Head Ex-NFL players commented:
'Damn Right It Did. Give the Man his Money!!!'
Despite Jackson's position and the Talking Heads' commentary, every QB that signed a big-$ extension after Watson, received guaranteed money that represented about 70%-75% of the contract total.
Eventually, Jackson signed for about $260M, with ... Wait For It ...
70%-75% guaranteed.
