Name any fighter from 140-154 that can give Floyd a run for his money.

Manny, Lara, Thurman, Bradley.

[DreamMerchant12]

Only one I can really think of right now is Erislandy Lara.

[shenmue]

Marcos Maidana. may 3rd Floyd and all the doubters will find this out.

[White_Knight]

Lara, Trout, Pacquiao, and Bradley.

[AntonTheMeh]

may be a little to early to say porter, but that kid's the goods.

Better yet, let's name all the fights that would have been tough that he didn't take.
Margarito...Floyd would have to move for 12 rounds cause Tony was a beast with an iron chin...

Prime Oscar....great fighter who ducked no one..would have been a super close fight...I'd take prime Oscar.

Prime Shane....fast,strong....also a steroid cheat so who knows...

Prime Cotto... Floyd still beats him

Manny.....still has the speed and volume punching..and he's a southpaw with power

Lara......we will see how good he is soon

Paul Williams....I think Floyd loses this one

Kostya...I'd take Floyd but it would have been a tough fight

Cassamayor...this guy was the real deal back in the day..don't know why they never fought as they were in the division at the same time with Castillo,Corrales, and Freitas.

I will get clowned for this but here me out...
James Kirkland!!!!! Yes his chin is suspect but Floyd isn't the biggest puncher. He truly has the size, temperment and spartan training to have the balls to the walls style that would give Floyd fits. With Anne in his corner he would truly have the IDGAF attitude to keep coming through the hailstorm of Floyd's punches. That rabid ravaging of Tapia was scary.

[Uklad]

Khan,Manny,Bradley,Porter.

[Scary]

Manny Pacquaio and Amir Khan.

The other new guys like Thurman and Lara needs an elite fight before I'm able to judge, haven't seen much of their career building fights.
