My concern with Genie is that I don't know how far she can go with out significantly upping her power and adjusting her game. Sam is a great coach, but Genie is a prime example of a player that would greatly benefit if tennis had a true off-season. She could work on her fitness to increase her power and Sam would have time to tweak her game. I know some people will argue that her results from 2014 are enough to prove that she doesn't need to change much, but I challenge anyone to look at the players she actually beat to reach two semis and a final at majors in 2014. Genie beat players like Larsson, Kerber, CSN, Soler-Espinosa, Cornet an injured Halep and Ana (no offense SP). Those are really talented players but IMO beating them gave Genie a false sense of where her game actually stands against the elite players.
