I don't think either choice is simple, but what can you do? You figure out which one will have the best short- and long-term prospects. Also "firing" someone isn't as simple as you think either -- chances are there were bills to settle. One only has to look at the Canton situation from last season to see that at play. Igor is a richer man because the Canton folks fired him without going through the proper protocol.
You have to be careful and make sure you have just cause before firing someone.
Actually, coaching situation changes are much simpler than "firing" (and in some states, firing is fairly simple since it's "at will employment"). You inform the coach you wish to discontinue working with them as of X date and that you will now be working with coach Y (if you already know) or that you will be searching for a new coach. Then you make sure your bills are settled. Then you are done. Then you have a trial with your preferred new coach(es) then you decide. Period. Very simple in theory. Of course, there's the usual emotion and angst which surrounds these kinds of things, but still, not the same as firing. The new coach(es) will contact the previous coach to ensure the student has informed him/her and that they are current on bills. This is how the PSA by-laws are written.
TSL put everything out in public to no fault of Gracie, Alex, or Frank (as far as we know) before this was a done deal and aired the "process laundry" which was inappropriate in some respects.
Everyone is waiting to hear about how the "trial run" is going with Frank and Gracie. Of course, according to TSL, the story is being twisted; they say the Frank/Gracie thing is a done deal even though nothing has been made official yet. Usually I'd take what they say with a grain of salt but considering they knew about the Frank/Gracie thing weeks before it made news, I'm thinking their source is mostly reliable. What has not been decided is whether Gracie is moving to LA or will go through with (the horrible idea of) bouncing back and forth b/w Canton and LA.
Per Hersh today (12:18 p.m. CDT, Sep 23, 2013):
Gold and Carroll had three working sessions last week, the coach said. ....
Carroll said he had no idea whether he would become Gold’s full-time coach.
A few new quotes from Carroll are in the full Hersh article linked above.
"Gold and Carroll had three working sessions last week, the coach said. One involved explaining his methods and his ideas on jump technique; one had a few jumps; and one focused on her short program music and choreography."
God bless this man for trying to do something with that awful short.
I'm very curious about the next step in Gracie'f future. Can hardly wait. But wouldn't it be great if she stuck it to all of us nosey internet people and didn't make an official announcement.
Maybe "focusing on the short program music and choreography" means dumping it.
If anyone can do it Frank can.
