Penn State's Saquon Barkley blowing up the NFL Combine yet again

Saquon Barkley is making this NFL Combine his personal showcase.

Despite even the slightest of stumbles.

Of course, the former Penn State running back was expected to test extremely well in Indianapolis this week during the biggest lead-up event to the NFL Draft.

And, sure enough, his quest to dominate the combine at Lucas Oil Stadium is coming true — and eliciting jaw-dropping reviews from around the league.

Watch Barkley's 40-yard dash (story continues below):

The NFL.com broadcast team was calling Barkley's workout "a complete freak show."

After crushing the bench press competition Thursday — his 29 reps at 225 pounds were more than most offensive linemen — he started Friday even better.

His 41-inch vertical jump broke his own Penn State running back record by three inches. It also was 1.5 higher than Alvin Kamara's top position mark at last year's combine. 

The "41" ties him for one of the top marks for a running back since 2006 — though no one in that elite group weighed as much as his 233 pounds.

At last year's combine only one player had 29 or more bench press reps and jumped 41 inches or more. That was No. 1 overall pick Myles Garrett, a defensive end. But even he ran a slower 4.64.

Barkley outdid that on Friday. He ripped off his first 40-yard time in 4.40 seconds, the second-best among running backs. His Penn State record is a blistering 4.33 (hand-timed) last summer. 

The analysts and play-by-play talent on the NFL Network were then calling for a sub-4.40 time on his second attempt. And he may have gotten it if he didn't stumble just a bit coming out of the blocks.

He still finished with a 4.42 mark, stunning for that miscue and his weight.

Meanwhile, NFL Network analyst Charlie Casserly tweeted that he hand-timed Barkley's first combine run at 4.28 seconds.

Barkley then finished with a near-flawless performance in his field drill, including pass-catching.

Barkley expects to be one of the top give picks in late April's NFL Draft. He's already said he would welcome a home with the ever-rebuilding Cleveland Browns.

"His lower body, power and explosion is as good or better than any running back I've ever seen," said NFL Network analyst Mike Mayock.

Is he worth the Browns' No. 1 pick in the entire draft? Over a franchise quarterback?

Consider that Barkley has shown NFL Combine watchers clear glimpses into his overall potential. He's displayed a rarely-seen mix of size, speed and athleticism. He built himself into a dangerous receiver by his junior year at Penn State, making 54 receptions.

He talked about that progress on Thursday.

"That's something I'm very proud of. From my freshman to my junior year, I increased my receptions every year. That's a challenge I took on. My coaches challenged me to take that on," Barkley said.

"That's where the game is going. If you want to be elite, if you break down the top five backs, all those guys can catch the ball. All of those guys are special with the ball in their hands. That's something I strive to be. I want to be one of the best.

"I want to show that I can run routes. I ran routes in college a little bit. But I want to show I can run a zero-to-nine route tree."
