Florida State football returned to the practice fields Tuesday morning as preparation for Duke continues.

The Seminoles' normal game week schedule has moved up a day to accommodate for the Friday matchup vs. Duke. Tuesday's practice felt a little flat in comparison to the display on Monday, there were some good things done, but it felt like a lot was left on the table on the practice field.

"It was good to get back out today," FSU head coach Mike Norvell said. "It's obviously a big week for us to see growth and see improvement. I thought our guys did a good job with the plan and what were asking them to do. Obviously continuing to improve on the details and the fundamentals, but obviously it still comes down to the execution."

Here are three things to know from Tuesday's practice:.

A slower, yet solid day from Brock Glenn, Luke Kromenhoek

Both quarterbacks had far more ups than downs on Monday, however, during Tuesday's practice Brock Glenn and Luke Kromenhoek had a slower, yet productive day.

Glenn started the day well, making a couple of nice early passes in 11-on-11 work. However, after some missed time routes and pressure forced by the defensive line, Glenn struggled a bit to connect with his receivers.

He bounced back with a better performance in one-on-ones, and despite some drops (again), he managed to complete some high-level passes. He connected with Ja'Khi Douglas on a nice throw in the middle of the field and then he found Jalen Brown in redzone work with a well-placed throw.

Something that stood out was his leadership, there were a few instances of him going up to receivers after either a drop or miscommunication and talking it out with them.

Kromenhoek made some really impressive throws look easy, but still struggled in the ways you'd expect from a freshman at times. In one-on-ones, the true freshmen connected well on a couple of deep balls to Brown and BJ Gibson respectively.

He showcased his arm strength and made some good decisions in team activities. There were a few throws that left more to be desired, but overall the big plays show you the potential Kromenhoek has.

Inconsistency offensively, struggles with the 50/50 ball

Drops were again present, and more importantly, struggles in winning 50/50 balls.

The latter is something that hasn't been a huge issue to this point, but it was present on Tuesday. While the defensive backs had a really impressive day, the wide receivers lacked an edge at times when fighting for contested balls.

There were a few occasions where the receivers showed some fight. The standout one was when Douglas won a rep in red zone work, ripping the ball away from the defensive back who thought he had an interception.

The consistency just wasn't there, however, as too many balls ended up in the turf or in the hands of the defense. There were multiple occasions a pass bounced off the hands of a receiver - be it they weren't ready or the throw was too high or behind them - and it ended up in the hands of a waiting defender.

A few players had some strong days. Brown, Douglas and Gibson were the standouts, with the trio all coming up with some big plays on the day.

FSU's secondary has a big day

While the offensive struggles came in part to the inability to hold on to the football, the Seminoles' secondary didn't give the receivers much time to think.

Coverage was strong and the defensive backs were extremely active in pass defense. They were almost too active at times with Norvell even telling a few defensive backs to watch their hands in one-on-one work.

However, it was an impressive day for the unit.

Azareye'h Thomas locked down his assignments and even came up with an interception on a deflected pass. Both Quindarrius Jones and Kevin Knowles have continued to impress with more opportunities.

Knowles in particular has been impressive this week, making big plays both on Monday and Tuesday. Facing a Duke team that isn't afraid to let the ball fly, the Seminole secondary could carry some confidence into the game.
