It's possible significant changes are coming to Columbus on the heels of its dominant College Football Playoff and National Championship showing. The Ohio State Buckeyes haven't been able to celebrate even a week before suitors emerged for some of their top playmakers and coaching candidates.

Already, we've seen Jim Knowles eyeing another opportunity, LaAllen Clark interview elsewhere, and Carnell Tate wooed by Oregon and Texas. Now, offensive coordinator Chip Kelly could be in the mix for several NFL openings. 

Recent coaching moves across the NFL have opened some unexpected doors. Kelly interviewed with the Las Vegas Raiders and Seattle Seahawks last year. He could be the prized OC for several openings this offseason as well.

Houston fired Bobby Slowik on Friday, and DeMeco Ryans previously praised Kelly as someone who taught him a lot about the game. 

"For me, it was fun playing for Coach Kelly," Ryans said of the coach who called him Mufasa. "It was a new style of play that was brought to the NFL and I was happy to be a part of that new approach — not doing everything just because it has always been done one way. So I was happy to be a part of that, that kind of a new regime. Seeing how we had some success early in the first couple of years, just didn't get it done these past two years as far as making the playoffs. Which, you know we still had opportunities to in both seasons — to make it to playoffs — just didn't play well enough and didn't live up to what we were capable of doing."

"Each player is different," Ryans explained when asked about Kelly's people skills, or lack there of. "I didn't have any issues with talking to Coach Kelly or you know, or even just shutting me off. I always talked to Coach Kelly, I always had a good relationship with him. So I think with each individual player you may have something different to say. And it's not to say that that style doesn't get it done. I think there is a ton of different styles and different personalities that work in the NFL. I see guys like Mike Tomlin, who guys go out and I see their team having fun. You know, guys really play for him and they have fun doing it."

It would certainly make sense for Kelly to rebuild the Texans' offensive line and run the game as he did for the Buckeyes and give Ryans a trusted, veteran eye. Plus, working with CJ Stroud? It's hard to go wrong.

But the Texans could see competition from a divisional opponent. CBS Sports' Jonathan Jones reported that Kelly is someone to watch for Liam Coen's OC role in Jacksonville. 

Both Kelly and Coen run similar offenses, sticking to a lot of 11 personnel and using motion to create advantageous run angles. It'd be interesting to see how much influence Kelly would have here, though, as Coen will surely want to stick with more gap schemes and slower tempo compared to what Kelly has generally utilized in the past. 

Would Kelly already bolt from Ohio State after one season? Most fans were frustrated with some aspects of his game plans, but as an X and Os and film guy, I thought he did an excellent job blending his own concepts into Ryan Day's passing foundation and situational tendencies. That's a tough task, and by the Playoff, the two worked well in unison.

The relationship between Day and Kelly shouldn't be underestimated. Coen doesn't have the same personal bond with Kelly as Ryans and Day do, so that might be a factor in how that plays out.

As with Knowles, the Buckeyes can surely have their pick of the litter to replace him. They first landed Bill O'Brien for the role last offseason before he landed the Boston College job.

The Buckeyes could theoretically look at Ryan Grubb, who uses the pass to set up the run, or promote Brian Hartline.
