Just listened to the Bo Nickal podcast with them from last month. Conner says he tops off at 205 and is just over 197 after practice. Cole says he's 225 and hoping to get to 235-240 by the start of next season.
Not sure how you get that from what I said - some guys transfer every year, so no. It depends on the transfer credit policy at the destination school; not every school allows unlimited transfer credits.
The more academically competitive schools limit the number of transfer credits allowed. So you can transfer after one year or as a grad. transfer, but not in between.
You can't assume it's the best training environment just because it's PSU.
Maybe the coaches only focus on their stars? Maybe Barr doesn't like to train with him? It's a successful environment for the starters but that doesn't necessarily mean it's the best for backups.
PSU has Barr at 197 and Welch at 184 (doubt Mirasola could make 184 anyway). Why isn't this kid in the transfer portal? He could be a 4xAA for some other team.
