LSU offensive line coach Jeff Grimes instructs his players during a Tigers game. Thursday morning, BYU announced that it has hired Grimes to become the new offensive coordinator at BYU.

BYU welcomed Jeff Grimes back to its coaching staff on Thursday, as the former Cougars offensive line coach was named as the team's new offensive coordinator.

The news sent fans and former players alike to Twitter to share their thoughts on Grimes, who served as LSU's running game coordinator and offensive line coach from 2014-17.

Several former BYU players who suited up for the Cougars during Grimes' first stint at the school (from 2004-06) shared their optimism over the hire.

Another former Cougar sees it as perhaps more of a short-term hire.

Former BYU tight end Chad Lewis, now the Associate Athletic Director of Development at BYU, also shared his congratulations about the hire after reports surfaced of the news Wednesday night.

Grimes' hire also garnered a welcome from Cougar defensive end Sione Takitaki.

Former BYU offensive lineman and radio personality Hans Olsen broke down what Grimes is leaving at LSU, and what the conclusions could be for BYU and Kalani Sitake's pitch.

A pair of Cougar fans shared their thoughts on how the move could show how BYU is overcoming obstacles the program faces.

There was a BYU basketball crossover comment as well. Could Grimes have the same effect for football as Heath Schroyer has had initially for Cougar basketball?

A lack of offensive coordinator experience for Grimes does make some give pause to the hire.

An LSU fan shared his thoughts that BYU would be getting a solid offensive coordinator and lists Grimes' accolades as an offensive line coach for the Tigers.

This BYU fan called out for Twitter coaches to send ideas his way.

Which developed into a conversation about BBQing.

The announcement, of course, brought out some rivalry talk.

And the hire just wouldn't be complete without a Simpsons GIF:
