After the first weekend of college football, some first impressions:
■ Johnny Manziel has behavioral issues. Still.
■ "Famous" Jameis Winston, Florida State's redshirt freshman quarterback, is my new favorite player. (And no one would blame Mark Stoops if he wishes he still had some of those Seminoles defenders.)
■ To Bobby Petrino, play-calling is like riding a bike.
■ Former Western Kentucky coach Willie Taggart does not mince words, as proven when he called a 53-21 loss to McNeese State in his South Florida debut "a nightmare" and other descriptions inappropriate for a family newspaper.
■ Clemson's offense is outstanding, but its defense is a worry after Georgia gained 545 yards.
■ Accused of taking plays off against North Carolina, South Carolina's Jadeveon Clowney will turn it on Saturday at Georgia.
■ Given Louisville's schedule, Teddy Bridgewater may set an NCAA pass completion percentage record.
■ Tommy Tuberville, a 42-7 winner over Purdue in his Cincinnati debut, will enjoy the Queen City, and vice versa.
■ Former UK receiver/kick returner Derek Abney heard his name mentioned over the weekend when Alabama's Christion Jones became the first major college football player since Abney in 2002 to return a kickoff for a touchdown, return a punt for a touchdown and catch a touchdown pass in the same game.
■ Ole Miss true freshman receiver Laquon Treadwell will trace the SEC footsteps of A.J. Green and Julio Jones.
■ That yellow "Windows" advertisement icon at the bottom of the screen during ABC's Saturday Night Football telecast looks too much like the "flag" graphic the network uses. Very distracting.
■ After surviving the departure of first Rich Brooks and then Mike Bellotti, Oregon appears determined to survive the departure of Chip Kelly.
■ With an off week to iron out its problems, Alabama's offense should be ready to roll when it hits College Station on Sept. 21.
■ Thinking the first half was over (the officials said it was), TCU mistakenly entered its locker room (the officials were wrong), then was forced to come out and watch LSU kick a field goal. First-game jitters for everyone.
■ Nebraska needs improvement on defense considering the Huskers have given up 1,831 yards over their final two 2012 games and their 2013 opener.
■ Because SMU outgained Texas Tech 490-461, new passing game coordinator Hal Mumme probably thinks the Mustangs won. (They did not.)
■ Washington, a 38-6 winner over Boise State, could be this year's sleeper.
■ Apparently 73-year-old Kansas State coach Bill Snyder is not old enough to know that if you are going to schedule an FCS team for your opener, avoid scheduling the No. 1-ranked FCS team, i.e. North Dakota State.
■ Surprisingly porous a year ago under Mike Stoops (brother of Bob and Mark), Oklahoma's defense could be back to being Oklahoma's defense, given its blanking of Louisiana-Monroe on Saturday.
■ With two of its best defensive players suspended and its coach angry at the media — some Florida news outlets reported that another Gator was suspended; he wasn't — Florida held Toledo to six points and showed it will be a tough opponent.
■ While up-tempo offenses may not cause injuries, they apparently do cause defensive players to cramp quite often.
■ Speaking of cramps, why is it that 64-year-old Diana Nyad can swim from Havana to Florida but college football players can't make it through a hot Saturday afternoon or evening?
■ We should watch Notre Dame-Michigan this Saturday before the never-ending college sports money grab drives another great rivalry into extinction.
■ Last but not least, Johnny Manziel will tell you it is foolish to make snap judgments one week into a season. In his 2012 opener, Manziel failed to throw a TD pass in A&M's 20-17 loss to Florida. He proceeded to win the Heisman Trophy. (And the trouble began.)
