Fowler Power source

Looking at some video of Fowler I notice something that I think is a huge ingrediant to fowlers power and that is the mobility of his thoracic spine. Look at the lines I drew on his chest and back. The thoracic spine moves forward and backward in the rib cage and at the top of his backswing look at the extesion he gets and how expanded his chest is. This is what helps him to generate tons of speed.

i know he pounds it out there. very different type of swing. he definitley looks to be swinging faster then anyone else on tour. totally opposite RST.

Have to totally disagree he keeps his arms in front of his body after looking at the vid below.

He definitely lacks in shoulder elevation at the top of the backswing (top of right arm below shoulder level).  That would be closer to RS1 as he leaves his arms deep on the first move down.  To be fair, the 114mph swing speed that they commented on during the Sunday round was only one swing.  He may not have been swinging at full speed for that particular drive.  I also believe he was ahead of Camillo and the other guy they were playing with when he hit the lay up shot on 15.

arms swing across his chest. no shoulder elevation. super flat. im sure he clubs are bent upright severly. not saying hes screwed up and cant hit a ball becuase obviously hes on tour and competing! i just dont think he is a RST model. his downswing does have a lotta pull to it but other then that i dont think much else compares to RST. im sure chucks 13 min analysis will explain the goods and bads much better then any of us can.
