Nothing. None whatsoever.
There is nothing you need to worry about Mike's position other than her speed relative to the other members of your team. There had been this misconception (for god knows what reason) that Mike should be placed last so that the team may get a head start next cycle, but this is only half true, as people have forgotten that she also carries the speed of those placed behind her.
Nice. You've managed to figure out the best correct answer for your superstition *pachi pachi pachi*
