SSF saw some players competing without any coach or their regular coach.MK/HS were coachless.MAS players had coach assistants to guide them while the Danes had compatriots to look out for them.The outcome: 1) MK/HS did not play badly but they had a harder time defeating their opponents, with most matches stretched to rubber.Eventually they lost their last two matches, also in rubber.There was no doubt they were in rubber shape after the last point but they could still smile with their eyes when I saw them.Having a coach definitely makes the difference between winning a title or none.At least MK/HS now knows that. 2)MAS couple, LCW and WMC both had coach Tay while coach Pang was super busy with the MD,WD and XD.The performances were excellent even when they lost.For the first time, even MAS media wrote about MAS WD's fighting spirit instead of 'weak mentality'.It was interesting that the MAS players who won titles said they did not train 100% but had more 'rest' as they were looking at SSF more like a 'working holiday'. But I must say both Tay and Pang did a splendid job.In fact, they may be more effective than Rexy and Misbun because they are more like brothers to the MAS players,hence more rapport and calmimg effect.Whereas Rexy and Misbun are more fatherlike figures, thus more stressful and less positive effect on their charges.So maybe better for Misbun and Rexy to stay home as training coaches while Tay and Pang guide as tournament coaches. 3)I asked Laybourn how effective are teammates as coaches.He said good enough because as professionals they can also be coaches.Maybe fulltime coaches have better insights but he does not think the difference would be significant.But a coach is definitely a plus, even when playing well; if only to give a pat on the back and say,'Keep cruising'. According to fastdrop, Dicky Palyama reckons a coach can contribute 20% difference to a player's performance.From one, even 30%.In fact, fastdrop noted Sony had 3 different coaches for 3 recent SS with 3 different outcomes.
