I do not doubt that Chambers can put up these kind of numbers. The problem is for him to put up these kind of numbers it means Miami QB(s) will have to try and throw him the ball between 135-155 times and a numbers of those will result in pics by trying to force the ball into him since he doesn't get consistent separation or shield the defender from the ball well.
The other way Chambers has been able to put up big numbers is when the opposing team plays soft which means Miami is losing at the end of the game or finds themselves in 2nd or 3rd and long. It is sort of a catch-22...by rooting for Chambers to get his numbers it is almost like rooting against Miami.
Hopefully, Cam will not call Chambers number as much and the ball will be spread around to Hagan, Ginn, Booker (both), Martin and Brown.
