$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.
