"AB is a man of failure. Just a series of repeated failures."
That's Logan Paul going OFF on Antonio Brown ... saying AB is ducking him when it comes to their proposed celeb boxing match!!
"I'm a man of action," Logan tells TMZ Sports ... "I'm here to make money and win. And, AB is consistently losing and getting rocked by life."
Paul and AB appeared to have an agreement to fight each other this year ... but Logan told us out at Dan Bilzerian’s Angels & Devils Party on Thursday talks have fallen through.
