Josh Gattis hasn’t been a Michigan Man for long, but he sure hasn’t wasted any time in fitting the part.

Penn State wide receivers coach Gerad Parker tweeted a video of some receiving fundamentals over the weekend, which isn’t unusual at all for a position coach to do. Fellow assistants Sean Spencer and Matt Limegrover are two of countless coaches at all levels across the country who show off the skills they’ve taught with short Twitter videos.

THE PENN STATE WR GOLDEN RULE:

1.  If the DB is where you want him to be: LEAVE HIM THERE
2. If the DB is where you want to go: BRING HIM TO YOU

Gattis, who served as Penn State’s wide receivers coach from 2014-2017, seemed to take issue with this and decided to patronize the Nittany Lions’ newest addition to the coaching staff in response:

It’s a 3 rule plan used since 2010! The “golden rule” was have a plan=identify 4 type of press+ use rules of release! Glad it’s still of use!

“If he’s where you want him, leave him there!
If he’s where you want to go, bring him to you!
If he’s on your line, get him off!”

The 3 rule plan was taught by one of the best I ever learned WR play from @coachjohnshoop !! I guess I found another member of the tree lol! He has shaped many @GeradParker1 and taught us all the importance of the Craft!

Gattis left Penn State’s program for the same position at Alabama prior to the 2018 season. After helping the Crimson Tide reach their fourth straight national championship game, Gattis left Tuscaloosa for the offensive coordinator gig at none other than Michigan. His return to the Big Ten means that he, of course, has to bicker with his new “rival” (although James Franklin may not agree with the use of that term).

Why Gattis decided to quip back at Parker isn’t exactly clear (maybe he’s still mad Ricky Freakin’ Rahne got billed as coordinator over him), but rest assured that the newest member of Penn State’s coaching staff didn’t take the bait. He responded to Gattis’ second tweet, albeit in a very polite, respectful manner.

Another great example of how close knit this profession is. Good to talk @Coach_Gattis and clear up how our teachings crossed paths with the great @coachjohnshoop

This isn’t the first time Gattis has turned heads for the wrong reasons with his use of Twitter. In February, Michigan’s offensive coordinator declared his new team as “Tight End U” by cherry-picking other teams’ stats at the position. In order to make his claim to that title seem somewhat credible, he didn’t include Iowa, which produced not one, but two first-round NFL Draft picks at the position this year, in his graphic.

It’s safe to say Penn State fans didn’t take Gattis’ thoughts well:

Kinda petty… Its football. A lot of coaching techniques are the same.

Kinda weak sauce my guy.

At the end of the day, Gattis’ worst crime on Twitter isn’t looking down upon the guy holding his old job title or leaving the real “Tight End U” out of a graphic. We’re deeply saddened to report that he blocked your favorite student-run news outlet.
