I did give that a lot of thought, George, but the consensus on forum around the time team talks were introduced was "If you want to make tactical changes at half-time, you've got the tactics screen to do that with, team talks should be something else."
I'm not so sure, myself - I remember a
lot of my youth-football experiences, especially once we hit the higher levels, it was always a tactical discussion at the intermission as well.
I'd at least like for that to be a possible persona, in-game - as I said, the "Professor" approach.
I'll touch on some of the other responses later.
