Wolf will not improve. What really has he improved since 2007? He doesn't have the Ronnie Coleman drive to beast out. Why should he.
...
You cant see the improvements from 07

The guy is wider through the back - no one can beat him in width , his lower lats have improved
but this is always going to be a weak area as it's genetic but theres been huge improvements for someone at his level.
Calves ? well again genetic but Phil has a shit chest and is narrow yet doesn't seem to be marked down for this , that is more important than
weak calves don't you think ?
His taper ruins everyone on stage and that is what the best built man in the world is meant to have - look to the roots of BB. The X frame is superior
and what should be awarded the medal of Mr Olympia.
You said he lacks pop ? the one pose that shows the most pop is the most muscular and he is well known to own this over others , so no pop to the muscle is silly
when the one pose that shows the most pop to the muscles he dominates in.
