There are several differences between the 4-0 preseason in 1991 and this year.
1) Bugel wanted to get his starting offensive line to work together and placed them at least an entire half in each game.
Mac got his starters out of there much quicker this year and wanted to see the backups quite a bit more.
2) Most of the Defense comments talk about our speed. This will not go away in the regular season.
3) Most of our rookies this year seem ready to play and not require years of development before becoming NFL caliber players.
4) Jerry Sullivan seems to have a plan on what he wants to accomplish and makes sure the team works according to the plan.
5) We believe our overall depth is better this year and the win at Minnesota shows our backups can play.
