Power Sweep has something in their bowl writeups about avg OL and DL size and weight. I'm not sure if it is accurate in terms of who actually plays or rotates (while not counting certain players who are out for the bowl), but that is an interesting thing to consider if it is somewhat accurate. For instance they have the Toledo OL avg weight of 299 and the MTSU avg DL weight of 260. Toledo OL isn't that great so if they can try and overpower smaller DL that could be an edge, unless MTSU DL possesses some kind of quickness as a counter.
