COLLEGE STATION, Texas — Texas A&M's 56-24 win over Vanderbilt showed us a lot. Here are three things we learned about the Aggies from their performances:

When it's intact, the defense can perform: Well, it's not completely intact as the Aggies were minus two starting defensive tackles (Alonzo Williams, left foot, and Kirby Ennis, who's done for the year with a torn ACL), but there was enough personnel on the field that defensive coordinator Mark Snyder was comfortable with. So, he he dialed up blitzes. The results were positive: seven sacks, 95 rushing yards allowed, 329 total yards allowed and three turnovers.

Johnny Manziel can get it done without running: His ability to run is one of Manziel's signature traits, but he ran four only times on Saturday, partially to avoid taking too much contact on his injured throwing shoulder. The result was still pretty good: 25-of-35 passing for 305 yards and four touchdowns in basically two-plus quarters. He had one interception, but otherwise had a stellar day.

Changes aren't a bad thing: There were some lineup changes on defense and for the most part, they worked out well. True freshman Noel Ellis played well in his time at nickelback. Donnie Baggs hadn't started since Sept. 14 but did well in his return to the starting lineup on Saturday. And on offense, the offensive line saw some shifting because of an injured Cedric Ogbuehi. Jarvis Harrison moved from left guard to left tackle, Jake Matthews from left tackle to right tackle, and Garrett Gramling stepped in at left guard. Overall, it was hard to tell there was much of a difference as the unit performed well.
