The Fed/Wawrinka match today finally pushed me over to the other side of the on court coaching debate, firmly in favor of it now. If Wawa's coach were allowed to give him a pep talk at the tail end of the second set and at the beginning of the third he might have pulled off the upset. At the very least it wouldn't have turned into a route. Stan had a break point at 4-4 that he couldn't convert, so a pep talk in the changeover at 4-5 would have been huge. Also at 5-6 going into the TB. I'm not talking about time outs or anything, just 90 seconds worth of coaching during changeovers. Maybe Annacone could have woken Fed up in the first set when it looked like RF was still in his hotel suite. Discuss.
