Few things have gone well for Florida State football this season.

The Seminoles are 1-5 coming off a 29-13 loss to Clemson on Saturday. The team showed signs of improvement offensively with Brock Glenn under center against the Tigers after replacing an injured DJ Uiagalelei.

However, the same issues that have plagued the season were prevalent for FSU again.

The run game struggled to impose itself, the defense allowed too many chunk plays and struggled to contain a mobile quarterback in Cade Klubnik.

There was an expectation that those two areas specifically would be a strength of this team, but it hasn't been the case. Outside of those issues, there have been drops from skill position players and too many penalties and mental errors.

There have been a few bright spots to point toward this season for FSU, with preseason expectations unrealized.

So what has caused this?

From poor blocking, a lack of a run game and struggles in tackling, here is a look at the areas the Seminoles have struggled in this season.

Lack of explosiveness from the running backs, poor blocking execution

The most glaring issue that FSU has faced this season is its lack of a run game.

The Seminoles rank 132nd out of 133 Football Bowl Series (FBS) teams in rushing offense, averaging 58 yards per game. FSU ranks just .4 yards higher than last-placed Kent State (57.6 ypg) and is six yards a game lower than the next closest team, which is UCLA (64.2 ypg).

FSU averages 2.2 yards per carry and has struggled to set up a reliable rushing attack since its first drive of the season against Georgia Tech. It is one of the primary issues in an offense that only averages 273.5 total yards of offense per game, which ranks the team 125th in the country.

Seminoles head coach Mike Norvell lamented the run game after practice on Tuesday, giving a blunt assessment.

"When it comes to the run game, it's been awful. There are some reoccurring issues that have shown up," Norvell said. "If it's making changes, if it's making different adjustments, whether it's a scheme, a concept, personnel, whatever that is, we've got to be willing to make those changes

"It's embarrassing what our run game has been."

Lawrance Toafili is the only player to eclipse 100 yards, posting 230 rushing yards this season, with freshman Kam Davis second on the team with 68 yards. There is a lack of explosiveness out of the backfield with plays taking too long to develop.

A compounding issue is the lack of quality blocking from the offensive line and on the perimeter.

Too often pulling guards or linemen miss assignments, or just flat out get beat. Running backs are often facing pressure as soon as the ball touches their hands, having to try to craft an escape from swarming pressure.

In the cases that the Seminoles tailbacks do get out of the backfield, there has been poor execution on permiter blocking from wide receivers.

In the Clemson game, there was a moment late in the first quarter where Toafili bounced to the outside and seemed set for a big play. But wide receiver Kentron Poitier, instead of blocking, ran a route that left the defensive back a free lane to crash on Toafili and prevent a big gain. The moment summed-up FSU's efforts in blocking for the run game this season.

Blocking has been a huge reason for the run game struggles, and a fix would mostly require an improvement in that sense. There are moments when the blocks are right, but the runs lack quality leaving a potential big play on the doorstep.

The Seminoles have to figure out how to get that going consistently, be it another shuffle of the offensive-line or a different set of play calls for the running backs to utilize.

Trouble with the run, inability to get runners down on first contact

The rushing attack isn't the only struggle for the Seminoles, the inability to stop the opponent's ground game has been a concern since week zero.

FSU allows opponents 182 yards per game, ranking the team 109th of the 133 teams in rush defense. The Seminoles have allowed opponents to rush for 1094 yards this season in six games, one of 20 teams to have allowed over 1,000 rushing yards this season.

It has been too easy at times for opposing running backs or quarterbacks, with mobile quarterbacks giving the Seminoles trouble. Ball carriers average 4.4 yards per attempt, doubling FSU's running backs average of 2.2 yards per carry.

There have been struggles in setting the edge at times, and the Seminoles have had a hard time wrapping up ball carries on first contact.

The defense is allowing too many extra yards after broken or missed tackles. There was an improvement vs. both Cal and Memphis, but the Seminoles allowed for too many chunk plays against both SMU and Clemson.

The Mustangs recorded 204 rushing yards in that game and the Tigers posted 265 on Saturday. More importantly, the unit allowed 958 total yards of offense combined in the last two games, with more than a handful of big plays coming after loose tackles.

Drops, mental mistakes, third-down struggles

There have been quarterback struggles, there is no denying that. However, as Norvell has stated there are plenty of areas where the offense needs to be better outside of the signal caller.

Uiagalelei had some moments he'd like back, with six interceptions and a number of overthrows before his injury. However, he had too many passes thrown to receivers hit the turf as the pass catchers have struggled to hold on to the football this season.

That same trend was present vs. Clemson with Glenn under center. Multiple players made key drops, leaving about five extra receptions off Glenn's total and costing the Seminoles some chunk plays. Those drops have created difficult third-down situations, an area FSU has struggled.

The Seminoles have converted on 24 of the 83 third-down attempts, a .289% conversion rate and the 125th-ranked third-down conversion percentage in the country.

Norvell said that a lot of the drops come down to mental errors, and it is something his players have to work through.

"A lot of it is your mind. The technique and fundamentals, watching the ball, keeping your hands together and the catch and tuck," Norvell said. "You have to get out of your own mind sometimes, and I think that's shown up with a few guys that we have and you got to work yourself through that."
