Maybe I am missing something, but I don't understand how you can say all close duals are simply won by bonus pts and winning close matches, and that the pre-match coin toss does not matter. while I think Eagle26 explained it quite well earlier, below is a simple 4 weight class scenario...
Team A wins toss and elects to send 1st in even matches. Match starts at 126. Team A has solid (but not spectacular) wrestlers at 126 and 138, with JV back-ups available. Their 132 is not very good, but is competitive.
Team B has studs at 126 and 138, but is weak at 132 and 145.
Team B has to send first at 126, and puts out their stud. Team A counters with a JV kid, and Team B earns 6 pts. Team A then puts their decent 126 at 132, and he wins by pin. Score is 6-6. Team B then puts out their stud at 138, and team A again sends their JV kid to get pinned. Team B leads 12-6. Team A then wins by pin at 145, and the score is 12-12. Granted, Team B could have sent a JV at 126...but team A would have countered by sending their good kid (but not good enough to beat the state champ from B at 126), who wins by pin. The stud from B at 126 then pins at 132, so same net result of 12-12 after 4 matches.
However, instead nowTeam B wins the toss and selects even bouts. Now Team A must send at 126. If they send their good wrestler, he gets beat by the state champ from team B. Maybe only a decision, but at least a major...but if A sends out a JV back-up, B counters with a JV back-up who happens to be better. Either way, B is getting at least 4 points. Then at 132, Team B wins again, because A has used their pretty good kid against the state champ. Same thing happens at 138 and 145, and because of the coin toss, there is nothing Team A can do to avoid putting their really good (but not great) kids against those 2 state champs. End result? From those 4 bouts, Team B now leads 20-0, which is a big difference from being 12-12.
What could Team A have done differently? Sure, get better and avoid a pin, prevent bonus pts blah blah blah...but other than having your 2 decent kids fail to make weight and then hope to bump up 2 weight classes to avoid the state champs, there is nothing you can do to overcome the fact that you lost the match because of the coin toss. Oh, and by the way, you now have plenty of angry parents who did not get to see their kid wrestle because he was removed from the line-up because we lost the coin toss and had to bump up our 126 to 132...and the parents of the JV kid we fed to the wolf with the hope of avoiding a pin are not too thrilled either, because the state champ was perhaps a little too physical (taking out some of his frustration, as he was hoping to get a little challenge from the kid you had to bump away to save points).
Coin toss matters (way too much).
