Tega Cay's first game of the season against an unproven CUFC team may be won before they get on the field. The key to this game is who scores first. I expect CUFC to win this game and beat MPSC later in the day. So I agree with all your predictions.
However, I think the more interesting games are CESA Challenge playing Bridge. It will be a long day for both teams as the 2nd game is at 5:00 PM. I thnk the "older" Challange team will go down to the "93 Bridge team. The earlier game between the '92s will be a draw.
