He wants the bragging rights, ego boost, etc. of being the highest paid QB.
Yep, he already has more then enough money to have him and his decedents live the life of luxury.
Its funny, but I really thought Watson really screwed himself sitting out, what amounted to two 1/2 years but from a financial perspective he made out. He lost something while sitting out, he did not play very well. Maybe now with a season under his belt he'll come back sharper.
I think Lamar seeing what Watson did and is using that as a template, at the end of the day, whether he plays or sits out has no impact on me. I need to work, pay my bills and try to deal with what life throws at me. He can spend his time on the golf course for the rest of his life ¯\_(ツ)_/¯
