Isaiah McKenzie just threw his hat into the ring for that title in the NFL ... 'cause the Bills wideout gifted his fellow receivers custom arcade game machines for the holidays -- and they're awesome!!
McKenzie shared the presents with his guys on Thursday ... and you can see in video of the goodies, they're decked out in Bills colors -- with the players' pictures and jersey numbers on them too.
Isaiah got a machine for Stefon Diggs, Gabe Davis, Tanner Gentry, Jameson Crowder, and Khalil Shakir, plus one for himself. He also made sure to grab one for the team's WR coach, Chad Hall.
Each one had a bow on it -- and when the guys saw them, they went crazy.
