Of course, not all the responses were positive. After seeing the hefty contract with $30 million guaranteed for the former Steeler, there was some outrage on social media.
Former Raider, now analyst, Maurice Jones-Drew had some strong statements after seeing all the "people hating:"
It’s so funny to me to read all these tweets of people hating on @AB84. When players know their worth and exercise their power like the NFL teams they become problems and not savvy businessman.— Maurice Jones-Drew (@MJD) March 10, 2019
Even the NBA seems hyped about the move.
Oakland native and Portland Trailblazers star Damian Lillard reacted, "Yessir AB!!!! we on now."
And the Timberwolves are just hoping he doesn't become a "bandwagon" Warriors fan:
As for Antonio himself? Seems like he's loving the love, and Oakland.
He's already got five posts about being a Raider on his Instagram.
Welcome to the Town, AB!
