this may be a dumb question for some of you, but i have never had this explained to me...what is the big deal with moving an O-Lineman from say C to G or G to T or from the left side to right side...i hear it all the time and people make such a big deal about it and I don't understand why, i have never heard analysts or anybody explain why it is such a big transition...can someone please clear this up for me?
