The entire combine, to me, is a joke; the physical part of it, anyway.
Teams should just conduct interviews. It's fine if it makes sense (to me it does) to get all the kids in the same place so multiple teams can meet with them. But there's no reason for them to jump, run, lift, etc. There's enough footage for teams to determine how good the kids are at what they do.
I'd like to see more kids (all of them, eventually) opt out of the physical crap and do what's best for them and their future. Not what's best for the people making money for putting them through an unnecessary Westminster Human Show.
