No, has nothing to do with your location. You did not go to the ST page and reset it as directed above.

/////////////////////////Longish explanation///////////////////
You have this in every ST spot on your team
Dylan Rodriquez CPU
Kole Bradshaw CPU
Benny Adams CPU
Westley Godwin CPU
Carter Burton CPU
Marco Knutson CPU
Ervin Hollingsworth CPU
Gerardo Savage CPU
William Figueroa CPU
Jefferson Bateman CPU
Darrell Tran CPU
Multiply that number of players * 39. =429 players you are trying to submit for update(at least, some positions have more than 11 per spot) in addition to your defensive players and offensive players. Despite the separation of the depths, the submit still is pulling all the players into the submit.
My suggestion from almost 2 and a half years ago to fix this is still sitting in voting.
http://goallineblitz.com/game/forum_thread.pl?thread_id=4369626&page=1This is what happens when you buy a new team from CPU. The CPU controlled team does not have to submit a depth chart request via HTTP. So it can put in many more players than we can. There is a limit to how much data can be transmitted via an HTTP request (probably 1k, it's set on the server).
When you submit a depth chart change, it submits every single player in every single spot (via their player number+ position info). This has been seen when people were posting bug reports of the glob of spam they would see on their screen from the 414 error.
So lets say a player number is 7 characters long, plus maybe another 6 characters per position (guessing here, i don't have a copy of a broken submit to get exact numbers right now) you are trying to send 13 characters* lets say 600 total players= which is around 7800 characters plus whatever http info has to be included in the submit. Thats way more than the data limit allowed by the server and so the result is the 414 (assuming you have the ability to see error messages, otherwise it just fails) error message.
*Edit* Breaking it down between what to do, and then the section on Why it happens.
