How will Bofo save Chivas when Vergara fails to address the real issue in the team, the defense.?

As you know, apparently Bofo seems to be the only refuerzo for Chivas. To be honest, Chivas is a pretty offensive side, as Arias horrible tactics proved near the end of his reign, but Bofo is done for. His glory days are over. It is definitely an improvement though from the current Chivas team but the defense is the real problem. I'm sure some of you Chivas fans would agree. Scoring goals or creating them was never the problem for Chivas, it was defending. (just look at Chicharitos scoring tally) Indiscipline and inconsistency in the back were HUGE problems. Reynoso reminds me of those old dudes that go play in the park in the afternoons, and Galindo has never been the same. Magallon remains as the only consistent performer in the defense. What do you people think?
