The Foley/Beale combination as dual 1st receivers not working - it can only work if the 12 is prepared to take a back seat and allow the 10 to run the game and have the 12 only overcall in rare situations or if the 10 is tackled.
The Waratahs also have the half back problem - neither of their 1st choice options are that competent at this level, so having two first receivers further confuses two already weak halves who have a history of poor options (particularly Phipps). This has been found out in the past 2 weeks against opponents who employed flat, rushing defences (bordering on offside).
Go back a year and the Waratahs didn't have these issues. Just as you can only have one coach, you can only have one backline general at 1st receiver.
Add to that the mess at the tackle last night which further slowed the play down. It took me back 10 or 15 years. There were some tackles in the last 20 minutes where there would have been 5 or 6 players from either team, all on the ground, all wrestling for the ball.
No time, no space for very much at all.
