There are a couple ways to look at this: 1) How good is it for the sport? 2) How healthy is it for the athletes? We all agree that participation rates are going down. My personal feeling is that the season is too long and we keep families stuck in a gym all day and sometimes for two straight days for 3 months creeping into part of a 4th month (December, January, February, March). Personally, I think 3 week of prep starting in November followed by wrestling in December/January with season ending mid-February would be ideal. We are wrestling so much and for so long, the debate has shifted to the value of an athlete achieving 100 victories because kids wrestle so much more.
How healthy is it for the athletes? - To Crimsonblooded's point, coaches can adjust their season accordingly. But there is a lot of pressure by families/dads to keep going and if they don't wrestle as much as the neighboring school, then you risk losing that kid. In addition, injury rates seem to be going up. Unfortunately, they (dads and coaches) know very little about periodization and the value of rest/recovery on the body... that's not a shot, because I believe they're doing the best they can, but just not knowledgeable.
