... please list the multiple 197-pounders who have moved up and won national championships against guys who are 50-pounds heavier. Specifics to validate your point please. I'll provide my supporting material below on your claims.
As star-studded as heavyweight has been the last two years, its not a weight weight. It may not be the best weight, but it's hardly weak.
But let me drop some actual reality on you for a second. You bring up forfeits, which may actually be correct at the high school level (more at the highest and lowest weights), but at the Division I level, the data doesn't support the assertion.
125 pounds had the most forfeits in D1 duals this year with 23. That isn't the lesser extent (you'll see why in a second).
125 was followed by 157 and 197, with 17 forfeits each, then 285 with 11.
The least forfeited weight was 141 pounds, where only four forfeits in D1 matches were recorded.
This does not include the medicals, with wrestlers bailing out on tournaments, but situations where teams put athletes out on the mat.
Now, let's see if there were fewer heavies entered into the conference tournaments, since every team has the opportunity to enter someone there. Looks like 285 had just as many entries (77) as all the other weights, save one ACC weight where Duke had a late scratch and there were only 5 in a weight.
