I think Weidman is truly deluded, first of all thinking he should get the next shot after getting stopped in his last fight then making these silly comments about the fact it's embarrassing Bisping is the champ? What's so embarrassing about Bisping's record? I'm not discounting Weidman's record or saying Bisping's record is better but lets compare...
Weidman 13-1
Notable wins:
Anderson Silva (2 Controversial wins)
Vitor Belfort (Non TRT version which is awful)
Lyoto Machida (If I remember correctly, Machida came back strong in that fight)
Demian Maia (was a terrible fight)
Bisping 29-7
Notable Wins:
Anderson Silva (controversial win but imho he won 3-2, still more convincing then Weidman's Silva wins)
Luke Rockhold (Knocked him out)
Cung Le (beat him in the stand up)
Brian Stann (at the time was a big and convincing win)
In terms of defeats obviously Weidman has only lost once so will be interesting to see how he bounces back.
Bisping has arguably many controversial losses due to the amount of fighters using PEDS which include
Dan Henderson (the reason why Bisping gets disregarded as a top fighter?)
Wanderlei Silva (was a closer fight then people remember)
Chael Sonnen (very close fight)
Vitor Belfort (this Vitor was a killer, ask Rockhold too)
He lost a split to Rashad at light Heavyweight
Got out wrestled by Kennedy (Bisping was coming back from a year long lay off and eye surgery)
And obviously losing to Rockhold which he avenged
Hardly embarrassing? ...cue Bisping haters and H-Bomb Gifs...
