I remember a thread last year (or possibly 2003) that questioned Bollmans training technics with the O-line because sleds weren't used. I want to say an ex
OSU fullback from the 70s (name escaping me) contributed to the thread saying it was a mistake not to use sleds in practice becuase it taught the o-line to push together as a unit.
anyway... point is there are practice photos on o-zone that show the O-line pushing a sled together. Is this something new? Is Peterson taking a more active role with O-line development?
