I guess the argument for not firing him would be that he took over the team halfway through last season, led them to the best regular season finish in league history and then got pretty close to MLS Cup.
His only sins have been the first leg of the Atlanta series and the slow start this year, but like I said in another thread, all it takes is 1-2 wins and they are right back in a playoff spot since the standings are so tight. There is plenty of time to still grab a seed.
I think Armas is gonna get to stay until the end of the summer at least. I'd rather see Hamlett fired and a competent team-builder brought in.
