If I was a fighter I would probably pick Jackson or Couture at first thought but after hearing their pitches I would really lean towards Shamrock. When he started talking about him being retired and all his focus being on his fighters it felt like he would be a great couch.
You could also argue that Shamrock is over the hill though, and that a very succesfull modern day trainer like Greg Jackson would be the best choice.
