I'll add to what Thor already replied. It's a first world problem Penn State has, but they basically turned 1 recruiting class into two. Four of their seven recruits are pushing back a year, Lee, Michael Beard, Seth Nevills and Aaron Brooks. Lee, Beard and Nevills are all in Happy Valley training at the NLWC and Brooks is training at the Olympic Training Center in Colorado. This will help them develop talent and spread the years out to help them all fit into the lineup. Roman Bravo-Young is stepping right into the lineup at 133 and the other two, Brody Teske and Gavin Teasdale will wrestle in open tournaments and hold their redshirt until after the Southern Scuffle in January, just as Nick Lee did. One of those two will likely be PSU's 125 later this year.
For Joe, assuming he lands at 165, he has Vincenzo Joseph with two years left. He'll still have competition, but doesn't waste a year simply waiting.
