USC offensive tackle Zach Banner, a likely preseason All-American, is huge (6-foot-9, 360 pounds), smart and social-media savvy. So he's not likely to get into a battle of Twitter verbiage over the Trojans' marquee season opener against Alabama, the defending national champions.

That said, he is not going to let a comment like this from former Alabama and current San Diego Chargers offensive lineman D.J. Fluker completely slide.

Banner replied in three three Tweets, taking note, paying due respect to Fluker and Alabama and taking the high road, while being just a tad annoyed.

Good 4 him being a NFL guy getting in a college football talk but whatever. I talk with my pads. I see 2 Great Teams https://t.co/VyUb2dlvh0 — Zach Banner (@zachbanner73) June 20, 2016

Talking back to Fluker makes me look stupid because he was a 1st round, College Natty Winner. Stuff I want to do. But stay in the pros sir! — Zach Banner (@zachbanner73) June 20, 2016

So with that said, Alabama is tough, aggressive, and trained well. You will never see me say anything bad about them be4 or after the game! — Zach Banner (@zachbanner73) June 20, 2016

Anyone else getting excited about Sept. 3, the greatest opening weekend in college football history?

Banner, of course, rose to Twitter fame when he documented his ordeal while trapped with a teammate in an elevator.
