It's like saying...
"Vince Carter had a better career than Jordan"...
Scratch that...
"ISIAH RIDER had a better career than Jordan...now prove me wrong...and provide them reciepts and analytics pleighboi" 
Every ridiculous assertion isn't worth a debate breh
But i'll bite...mildly
For one,
Post prison Tyson's top 5 wins >>>>>> Broner's top 5 wins
EASILY
In what world is this that a divisional AND p4p all-time great is anywhere comparable to a career paper titlist like Broner...who's never even beat/held a legit lineal/undisputed champ, or beat anybody resembling a hall of famer or all-time great...never even beat an ELITE contender/paper titlist
The closest thing has gotten to beating an elite contender/titlist level fighter...is Antonio Demarco
A guy who was only rated #1 at Lightweight because fighters because 3 fighters had recently moved up in weight
Keep in mind, this is the
ONLY time Broner has ever beaten a top 3 fighter in his weight class...a guy who was only in the top 3 by default
Compare a career paper titlist, who's never even held a legit lineal/undisputed title, and has maybe two kinda sorta OK wins on his entire resume... to a dominant undisputed champ who cleaned out every top contender in his division and has two
hall of famers on his resume.
Broner isn't even the most talented, skilled & accomplished "underachiever of the current era"....Dirrell & Dawson >>>>>>>
I guess they better than Tyson too huh?
