Dirrell's chin?

[Majesty]

That was only his 7th pro fight.

People are so quick to call someone chinny because they go down early in their career. Ali went down early, Ward went down early and so did Dirrell. It doesn't mean his chin is crap. Andre Ward stood up to Miranda's punches pretty well for a "chinny" guy

...but since then Dirrell has been hurt. VS Curtis Stevens he basically ran the entire fight.

Ward has a bad chin as well, he got rocked by afew no namers and he got put down by Miranda who doesn't throw quick, sharp, punches...he's going to have to have a horseshoe up his ass to beat Kessler because Kess has big power and he's a very good boxer

Was Dirrell actually hurt against STevens?

No, he didn't even get hit in that fight if I remember right. People just take a lot of credit away from him for runnign or not standing and trading with Stevens when its up to Stevens to cut off the ring and close distance and he could do neither. Think Mayweather agaisnt Baldomir and you have Dirrell against Stevens, no risks taken by Dirrell in that fight so he gets a lot of flack for it.
