I think they are Hyping Pacquiao's Spar Session up! I saw some Video of it

And Pacquiao hasn't been over susceptible to the left hook as you are saying, he has only had troubles with the straight right hand, and on one occasion with Morrales the jab. Sure Marquez landed the left hook, but Marquez has a great hook that lands on everyone. I am not saying Oscar won't win this, he is a clear favorite, but he has been gunshy lately. Everytime Mayweather punched Oscar would cover up and not punch back, same with Steve Forbes, he was just lucky Mayweather didn't realize this earlier in their fight, and that Steve Forbes is also a defensive fighter. If he can't get off more effectively then he could be in big trouble against Pacquiao, especially because he isn't as light on his feet as he once was. My main point about Mayweather was that he was able to take Oscar's power if Pacquiao can do the same then Oscar is in for a tough fight, then again if he fights a similar style to what Marquez did against Pacquaio, Manny is fucked, If OScar is willing to stand there and use clever footwork then Pacquaio's offense will be totally neutralized, and Oscar will have a field with him.

Yes marquez landed that left hook and oscar will land it again just to refresh your memory oscar has longer reach and is considered a bigger version of marquez but with better defense.
