Kara is not Shalane, and should have been training differently. One size does not fit all - her move to train with Shalane hasn't really worked out - not that I think that AlSal is a great Marathon coach (yet anyway) either - we will see with Mo and, perhaps later, with Rupp.
Other than these two (Shalane and Kara), Desi is on the comeback trail from injury, and Deena has really just reached a point (much like Radcliffe, both the same age and background) where the training she did to run 2h19 and medal at the Olympics is no longer manageable for her. Who else is ready to step up? Lisa Uhl (as mentioned above) is one, who else? Neely maybe? (in which case Hanson's has at least focused on marathon development - see Desi).
To get more American women to a high level, (who don't have Shalane's talent, and she has yet to run a really fast one, ~2h20,anyway) these women need to be indentified in College and persuaded to continue on - this should be the job of USATF (athlete development by first identifying the potential talent) to direct athletes to various groups/coaches. The way it seems to work is that the shoe companies are responsible for identifying those athletes, and that isn't their job (sponsorship is). The NCAA doesn't have the marathon as an event, and it can be a longer process to move from 5/10 to marathon, than to increase track distance lengths. The 5000 has spillover from the 1500 (see Rowbury this year), and the 5/10 go together (or even steeple/5 or 10)).
Is Hasay really fast enough to be a player in the 10000m? If not, then grooming her for a marathon might be prudent.
Here are the prospective 10k/Marathon relationships for those doing high mileage, and or specific prep for the marathon (think Benoit-Samuelson/Drossin-Kastor/Radcliffe)- approx. 4.5x 10k time = marathon (men have a generally greater time relationship).
30 minutes = ~2h15; 31 minutes = ~2h20; 32 minutes = ~2h25; 33 minutes = ~2h30 (allowing for some degradation as you get slower). The point is that athletes finishing College need to understand if they have the requisite speed to be successful on the track (5k/10k), and if not then begin preparing (maybe even while in College)to handle to load to run faster for a marathon, so that years aren't wasted getting there.
While I think Handley is a little too young to make that transition (even with Cathy Schiro as a role model)- if she has the requisite 10k speed (see above), then at least she might be prepared and it might even help her 10k (too much speed focus in College for some types of runners).
I wonder what happened to Clara Grandt (West Virginia), as I thought that she might make the tranistion (had a good Boston, granted favorable conditions, a few years ago).
In an ideal model, athletes shouldn't have to leave their current coaches (like Uhl from Cory Ihmmels, as that WAS working)- Simpson going back to Wetmore as well - in order to develop and get sponsorship. It shouldn't be about feeding other coaches (the NOP ones, etc.) rather developing athletes in the best environment for them as individuals. Frankly (while it isn't their job per se) I see a lot of wasted talent and years of devlopment in the transition from College to the Pro existence. That so few Colleges (or coaches therein) have post-grad groups anymore is a major weakness of the US "system/structure". I don't believe that "super-groups" are really necessary in the way that they are being developed. Jerry S. had a number of his athletes as leftovers from Wisconsin - his additions (Lomong could developed anywhere in my opinion) haven't really (Shalane MAYBE being the exception, but she ran equally well under Cook) added much, except numbers of training partners, to his resume.
