Everyone in Sooner Nation knows how the 2009 season unfolded with all the injuries and misfortunes.
First, tight end Jermaine Gresham suffered a season-ending knee injury before OU even got on the field for a game.
Days later, BYU knocked out Heisman quarterback Sam Bradford and knocked off OU in the process.
That forced redshirt freshman quarterback Landry Jones to briefly take over the reigns.
Bradford made a return to the field against Baylor, before reinjuring his shoulder against Texas, which ultimately forced surgery and sidelined him for the remainder of the season.
The Sooners, of course, dropped that heartbreaker to Texas as well.
It was Jones' team from there on out.
And he showed flashes of greatness at times.
In Jones' second start after the initial injury, he set the school record for most touchdown passes in a single game when he tossed six against the Tulsa Golden Hurricane.
But there were also growing pains.
Jones tossed five picks in an early November game at Nebraska, easily his worst performance of the season.
These were in large part because of a lack of experience, but also due to the fact that he didn't come into the season knowing that the starting quarterback position was probably his job.
However, that's different this time around.
"Yeah, I mean, obviously Sam was a great player here, won the Heisman and all that stuff, but I mean now that he's gone, it's more like it's my team to lose right now," Jones said. "I feel like I'm having a pretty decent spring so far, just got to keep working and hopefully I'll get the starting job."
Hopefully he'll get the starting job?
That seems to be a given, but the comment certainly outlines what Jones said is already a difference in maturity that can also be seen on the field.
"Yeah, I mean, I can already tell the difference in the way I'm seeing stuff now and the way I was seeing it back then," Jones said. "Just getting the experience of playing in the Sun Bowl and playing most of the year last year [was huge]."
And apparently the first scrimmage went as expected.
"I thought I played pretty good," Jones said. "I mean, sure I missed some things here and there, but I thought I played pretty well, took care of the ball, so I was pretty pleased with my performance."
Jones' improvement will be a welcome change by OU in the fall.
