There are lots of theories on lifting. We have seen many of them over the last 10-15 years go through Nebraska. Some people claim simple lifts like bench, squats, power cleans....etc is what you need to key on.
I think in the 80s Nebraska started actually designing lifting stations that resembled actual moves football players made. Some claimed that was a huge development. I even think our HS uses some of those types of machines now and we are known for having one of the nicest HS weight rooms in the state.
The part I like that has been mentioned is that the players were able to give input on how much they were ready to lift. I'm not a big lifter but I would think that would be much more advantageous than a coach simply calculating it and giving you a sheet of paper telling you how much you are supposed to lift. Obviously, there would need to be good supervision to make sure some meat head isn't doing something he shouldn't. But, the personal input is important.
