In the midst of a four-game losing streak, Georgia Tech is making some major changes ahead of Saturday’s game at Clemson.

With the Yellow Jackets sitting at 2-7 overall and just 1-5 in ACC play, head coach Brent Key is shaking up his coaching staff.

Key has dismissed four staff members, including defensive coordinator Jason Semore, according to ESPN’s Pete Thamel. Defensive ends coach Kyle Pope, offensive line coach Allen Mogridge and wide receivers coach Jafar Williams were also dismissed, according to the report.

DBs coach Vinnie Sunseri is taking over defensive playcalling duties, while former Clemson star DeAndre Hopkins is being elevated to primary wide receiver coach.

After Saturday’s 44-17 loss to Louisville, Key was quick to voice his frustrations with his team’s performance this season.

“I am damn pissed off. Damn pissed off,” the head coach said. “The way we coach, the way we play, it’s embarrassing. It’s a joke. Starts with me. I know what the questions are when they come. Yeah, we’re putting everything into winning games. Don’t think for a second planning has not already begun on making this thing the program that our fans, our players, our boosters, administration and our alumni damn deserve.

“And I told the team the same thing. So I’m not yelling at one person in there. I’m not. But I am pissed off. Not that I haven’t been for a long time, guys. But it’s. So, our fans deserve better. Yellow Jacket Nation deserves better. Everybody that wore the white and gold deserves better.”

Georgia Tech has struggled mightily on the defensive side of the ball this season, especially when it comes to stopping the run. The Cardinals racked up more than 250 yards on the ground in its blowout win over the weekend.

This season, the Yellow Jackets are allowing 5.3 yards per carry, which ranks 126th nationally, and 227.1 rushing yards per game, which is 135th in the nation.

After being picked by members of the media to finish fifth in the ACC this season, Tech has come nowhere close to meeting those expectations and is currently sitting dead last in the league standings.

Last season, Key led Georgia Tech to a 9-4 mark, including going 6-2 in league play.

Clemson will host Georgia Tech on Saturday at Memorial Stadium. Kickoff is scheduled for 12:30 p.m.
