Statements from this episode (12)
Belch: STRIVR is the first true, really good VR use case
“I don't want to say this arrogantly, but to be honest, what we're doing right now is the first true really good use case for virtual reality.”
Belch: Spherical VR video camera hardware will be a commodity within a year
“Spherical rigs out there, but we were doing this, you know, 16 months ago when nobody knew what this stuff was, and here we are today, and it's gonna be a commodity in about a year”
3D computer graphics are not good enough for VR athletic training
“If we use a video game, a three D rendering to try to train athletes, it's not going to work, at least today. The graphics are nowhere near good enough.”
VR mental reps enhance real-time play recognition for football players
“Because you're literally on the field, and your brain is saying, I've seen this before. Not only have I seen this before, I didn't see it three days ago in practice. I saw it last night, and that's a really, really big deal.”
Stanford coach David Shaw gave Derek Belch $30,000 to launch STRIVR
“By now, Coach Shaw sits me down in December and says, if I were you, I would stop coaching. And here's 30,000 dollars to get your company off the ground.”
Belch: Four out of five pitched college teams bought STRIVR immediately
“So after spring ball ended, or in the, excuse me, in the middle of the two sessions that Stanford does, I went on the road, and I went to Auburn, Arkansas, Clemson, Vanderbilt, and Dartmouth. I went to those five schools in a seven-day period. Just got on a pl…”
Belch: Dallas Cowboys became one of STRIVR's first clients on the spot
“He bought it on the spot. So now you got four colleges, five colleges, and the biggest brand name in professional sports next to the Yankees who are your first clients.”
Belch: NFL backup QBs get only 3% of weekly practice reps
“During a game week, a backup quarterback, you can count on one hand how many plays he gets to run, and he has to be prepared to go into the game, and if you guys watched last weekend, five backup quarterbacks went in in the NFL in one week, okay, and those guy…”
Belch: STRIVR sacrifices video clarity for faster turnaround times
“So it's not quite Google jump because it is a full sphere. It's not as clear as Google jump is because it's Not the full algorithmic stereo, but that's okay, given the turnaround time that we have to deal with.”
Belch: Quarterbacks must make on-field decisions within 1.4 seconds
“So Andrew's gonna show you how fast a quarterback has to make a decision on a football field, for those of you who don't know, okay? It happens in about 1.4 seconds, and if you don't see it, you're dead.”
Belch: 2017 VR headsets lack the visual clarity for non-football sports training
“We know that the headsets right now are not ready for any sport other than football because the clarity is just not good enough. You can't take a real video of a baseball player facing a pitcher And have it be good enough for a trained hitter's eye.”
