roach can improve khan's power,speed,footwork but cant improve his chin...

a glass jaw cannot be improved but with good defense he doesn't have to take that chance.

The neck muscles can be Strenghtened etc so yeah it is possible to help a fighter improve hes resistance but in the way that Khan got KTFO and since he was already an olympic athlete idk if theres much room for improvement.

Pac has been dropped several times in his career including coming from a jab from Nedal Hussein....Lol...but guess how many KD's he suffered after hooking up with Roach?Zero.Nill.Never...The Barrera KD doesn't count since it was a slip though the stupid referee Laurence Cole gave it an 8 count. So the precedent is there. With better conditioning. balance, defense...yes, a punch resistance can indeed be improved. Khan for late TKO over Maidana. ;P

@ eagle- Since he started working with roach/pac , A MERE CON's original 135pd chin has now graduated to the 140pd division. ... courtesy of sparing with Pac no doubt. ....A MERE CON's may actually have been improved so much he maybe ready to graduate to 147. When conquers 140 and moves to 147 he becomes -----> -----> Jesus, you see Amir Khan versus bangers like Alvarez & Cotto? He should worry about Maidana, cuz Maidana will be all over him ...........I see Khan as the future @ 147. Right now Cotto kills him by KO ... Saul maybe 115-113 SD. ...........I do see Khan leaving 140 soon. His lanky frame has started to beef out with roach's conditioning and Ariza'a power shakes. ...........He will be saying goodbye to 140 in 6 months. Then its time for the big fights.
