The tweet was garbage, not accurate at all...

"...As noted in a tweet by Spotrac, Brown had needed eight more catches to unlock a $333,333 contract bonus, 55 more receiving yards to unlock another $333,333 bonus, and only one more receiving touchdown to unlock one more $333,333 bonus. All three bonuses would have amounted to $1 million..."
