Ex-Pats Star Troy Brown Calls Belichick Greatest Coach Ever

Bill Belichick is a flat out BETTER COACH than Vince Lombardi ... so says a guy who won 3 Super Bowls with B.B., former star wide receiver Troy Brown.

Brown joined "TMZ Sports" (Friday night on FS1) to shed light on how Belichick's Tom Brady-less Patriots are 3-0 ... under a 2nd and 3rd string QB.

What T.B. says is shocking ... proclaiming B.B. a better coach than the man widely considered to be the greatest football coach of all-time, Vince Lombardi.
