There is no shortage of intriguing quarterback prospects for the 2024 NFL draft with Caleb Williams, Jayden Daniels, Drake Maye and J.J. McCarthy, among others, standing out as potential first-round picks, and Michael Penix Jr. had the opportunity to bolster his stock during Washington's pro day on Thursday.

And he did just that.

The signal-caller quickly turned heads with his 40-yard dash time and vertical jump. Albert Breer of The MMQB noted he was timed at 4.53 seconds on one scout's watch and 4.56 seconds on another scout's watch.

That type of speed and athleticism stands out considering Penix was never much of a scrambler during his collegiate career at Indiana and Washington. He tallied 134 rushing attempts at two yards per carry over five years and 49 games.

Naturally, there was plenty of reaction from social media to his performance:

There were also plenty of teams there to see Penix, as Omar Ruiz of NFL Network noted more than 100 NFL scouts and talent evaluators representing all 32 teams were in attendance. Those in attendance also included Seattle Seahawks general manager John Schneider, as well as New York Giants head coach Brian Daboll.

Such a performance in the 40-yard dash surely didn't come as a surprise to Penix himself, as he told ESPN's Molly McGrath, "I ain't no bum. I want to show off my athleticism and prove that I can run when I need to."

Penix was largely a thrower in college and led the Huskies to the College Football Playoff national title game as a Heisman Trophy finalist last season. He completed 65.4 percent of his passes for 4,903 yards, 36 touchdowns and 11 interceptions.

That arm was also on display:

There are some concerns with Penix, as he is older than most prospects and will turn 24 years old in May. He also dealt with some injury concerns when he was at Indiana, although he certainly looked healthy and quick during Thursday's pro day.

Still, production was not a question.

B/R's NFL Scouting Department projected him as the No. 44 overall pick in its latest mock draft earlier this month, which was behind Williams (No. 1), Maye (No. 2), Daniels (No. 3), McCarthy (No. 8) and Bo Nix (No. 42).

Perhaps Thursday's showing will improve that outlook.
