The way I look at it, the only long period of time Chepo had with the group was prior to the Gold Cup, and that was a necessary win, so I'm ok with him not experimenting extensively with flexibility. I also think it's hard to both try out new players in standard positions, and implement new tactical schemes at the same time. Now that he's had the team for a while, and there is a large base of players that know what he wants, I see the next set of friendlies as a chance to work on that formation flexibility. Of course, who knows if he'll actually do it. The U23s, in contrast, have had a minicamp and Copa America together, a minicamp and Panamerican games, and will have a minicamp and Olympic qualifiers. It's a shame that team had the Quito incident. It'd be nice if the entire group was used to working/playing together.
