I think this is true. Akers, for instance, (IMO) made the US team better, for some time, after she was no longer the best (technical) choice for our midfield. Other players were totally amping Their games, in awe of Akers' effort to sustain her own. It is tough to judge these intangibles, especially on a women's team where the team chemistry counts for so much. It is a judgement call. The thrust of my initial post, and those subsequent, is that I think the US WNT is now too hide-bound toward retaining the old guard, and that there is not much support (given that we have yet to totally fall on our faces) from either the entrenched players or the USSF to push for experiment. That leaves any coach, new or established, in a fragile position.
