Not sure what the first two sentences have to dovwith anything.
As for the rest, Garrard was slated to be the "bridge" starter that year, and Moore was never a consideration. Once DG went down, and looking to the future, it made sense to go with the rookie, IMO.
That's more a matter of philosophy, than the names on the jerseys.
3. But here are my big questions. Why didn't he perform better in big games? Why was Aggie so disappointing under Tannehill? Why could RGIII elevate Baylor, Weeden take OSU to the BCS and Tannehill not even get Aggie to play to their potential? In fact, why was Aggie the most disappointing team in the country (initial ranking vs. final ranking)?
Texas A&M vs. Oklahoma Aggie goes into the lockerroom trailing 13-10 and gets the ball to start the half. In the next 10 minutes of football, Tannehill goes 3-10, throws 2 interceptions, and the game goes from 13-10 to 41-10 in those 10 minutes. Game over.
Texas A&M vs. Oklahoma St. Tannehill plays well in the first half and Aggie takes a 20-3 lead into the lockerroom. 3 Tannehill interceptions just kill their chances. Weeden leads a comeback, on the road. Tannehill chokes at home. Tannehill 3 INTs and BTW Weeden goes 47-60, 438 yds 2 TDs.
Texas A&M vs. Texas This is the biggest game in Aggie history. Aggie feels like Texas has forced them to the SEC. When Aggie tries to keep the rivalry going, Texas tells them to pound salt. Texas has a putrid offense that is built for Friday nights. Texas has 16 freshmen that will log minutes. Aggie faithful sense the victory, and they make plans for "the eternal scoreboard". Enter Ryan Tannehill. After Texas does their part by picking up 7 yards in the entire first quarter and Texas A&M goes up 13-0, Tannehill leads Texas to the victory. 20-49, 224 yds 2 TDs, 3 INTs, with one of those INTs going for 6. Literally the only way Texas wins is if Aggie chokes it away and they do.
So to wrap it up - stay away from Tannehill. That collar gets tight when the game is on the line. In the Big XII - he is called "1 Read Ryan". If you take that 1st read away and make him adjust - he throws the pick. With Aggie rated in the top 8 in most preseason polls, in their 3 biggest games, all 3 choked away.
