Things I know and think I know:

Let's say you're a Nebraska football fan assigned to approach Ameer Abdullah with reasons he should return to school instead of jump to the NFL.

One area you might want to highlight: His Husker legacy.

Do college players really worry about their legacies?

Just wondering, because with 904 rushing yards in 2014, Abdullah would pass Ahman Green for No. 2 on Nebraska's career list. With 1,804 yards, Abdullah would pass Heisman Trophy winner Mike Rozier as the school's career rushing leader.

Abdullah rushed for 1,690 yards this season, the fourth-best single-season total in school history. He excelled behind an injury-plagued line and "in arguably the toughest run-defense conference in the country," Nebraska running backs coach Ron Brown said last month.

The 5-foot-9, 190-pound Abdullah carried a total of 549 times in the past two seasons. A body can endure only so much pounding. Indeed, you hear it all the time: A running back in his 30s is an oddity. So, no question, Abdullah has a lot to consider in making his big decision.

Thing is, he already has built a splendid legacy at Nebraska. But with another strong season, he could knock it out of the park. He needs only 673 all-purpose yards to pass Heisman winner Johnny Rodgers as the school's all-time leader.

No matter what Abdullah decides -- draft-eligible underclassmen have until Jan. 15 to declare their intentions -- I'll remember him for the honorable way he carries himself, and the marked improvement he made since arriving on campus.

Rozier arrived in Lincoln as the most celebrated of Nebraska's 1981 recruits. Green was thrown in with the first string early in his first practice.

Abdullah's profile was much lower upon arrival.

"He had great potential as an outside runner when he got here," Brown said. "But he now has the ability to run between the tackles and get after it. And he's become a good short-yardage runner.

"He's an outstanding receiver -- you can split him out wide. And he's gotten better in pass protection."

He still needs work on pass-pro. Maybe one could use that in an effort to lure him back to school. Just an idea.

* Abdullah said Dec. 31, a day before the Gator Bowl, he was aware some people wondered whether Nebraska's extensive list of injuries could be traced to Husker strength coach James Dobson's methods.

I have a difficult time drawing meaningful conclusions in that regard, in part because I've never witnessed even one Husker training session, and in part because, well, I'm not exactly Bruce Jenner.

Said Abdullah: "Dobson understands each person develops differently. He's done a great job individually with me, but also with other guys on the team. I couldn't be more supportive of what he's doing, and I'm just excited to see what else I can do with coach Dobson."

What else can he do? As in 2014? Hmm.

* Terry Joseph occasionally would say, "That's above my pay grade," when asked a question that strayed outside the realm of Nebraska's secondary. That line suddenly takes on added meaning with his hiring by Texas A&M.

Joseph and Texas A&M are a good match. His strongest recruiting ties are in the Southeast. It's difficult to coax the very best players in that region to the Midwest. And when Nebraska finds a diamond in the rough in the Southeast, a slew of other schools often follow with offers. My feeling was Joseph was inclined toward the South all along.

* I have no earthly idea how Nebraska coach Bo Pelini plans to fill his staff vacancy. But if he has a list of candidates, it should start with former Husker player and assistant Marvin Sanders.

Good luck finding an assistant who has a better resume and understands the lay of the land better than Sanders.

The 46-year-old Chicago native resigned as Nebraska's secondary coach in February 2011, with Pelini saying Sanders needed a break from coaching to spend more time with family. The Huskers led the nation in pass-efficiency defense in 2009 and were third in 2010.

Sanders is currently the head coach at Los Angeles Loyola High School, after a one-season stint as USC's secondary coach. At Loyola, he oversees a 300-player operation, including two freshman teams and a sophomore squad.

He lives with his family in Redondo Beach, five blocks from the Pacific Ocean. I'm guessing Sanders would leave behind the sun and sand if his good friend Bo sent another "Let's roll" text, as Pelini did in late 2007. Just a guess.

* Maybe Craig Bohl was getting bored winning all those championships at North Dakota State. I'm only half-kidding.

* RIP, Don Gill. I didn't know Don well, but I'm guessing I'm like thousands of others who feel like they did. I knew him well enough to say he was a genuinely kind soul. A true gentleman.
