What's your biggest strength as a player, and how does it show up in games?
My biggest strength is my vision paired with explosive acceleration through the hole and low-pad-level contact balance. As a running back, spatial awareness and reading leverage blocks happen in split seconds. I rely heavily on pre-snap alignment reads and post-snap keys, which allows me to anticipate cutback lanes before they fully open. This shows up directly in games on zone-read and gap scheme
What are you working to improve right now?
I am continuously refining my pass-protection mechanics and route-running out of the backfield. Being an every-down back at the next level means coaches need to trust me implicitly in blitz pickup—identifying linebackers, setting a firm base, and anchoring against power rushers. Additionally, I’m working on expanding my route tree to be a dynamic mismatch threat in the passing game.
What are you looking for in a college program?
I am looking for a culture that mirrors my own work ethic: highly disciplined, competitive, and detail-oriented. Academically, I need a program that supports rigorous time management and values classroom performance just as much as Friday nights or Saturdays. Athletically, I want a scheme that maximizes a running back's versatility—utilizing vision, physicality, and open-field decision-making.
Outside of your sport, what should coaches know about you?
Football is my passion and my standard, but I approach the classroom and my personal discipline with the exact same professional mindset. I understand that leadership isn't just about what you do on the field; it's about consistency, accountability, and how you carry yourself when nobody is watching. I treat my education as my primary foundation.
What do you want to study, and what career interests you?
I plan to pursue a degree in the sciences or business/finance. I genuinely love science and enjoy understanding how things work, whether that’s human performance, sports medicine, or analytics. My goal is to apply that same analytical, goal-driven mindset to a career in sports science, athletic training, or business operations.

Grinstead is a shifty back who does a nice job making defenders miss in tight spaces. He has the speed to get around the corner and turn the edge when a lane opens up. One thing I like is that he doesn’t seem to be in a rush. He’s willing to let blocks develop and trusts what he sees before hitting the hole. He plays hard, competes every snap, and strikes me as a pretty smart player with how he approaches the position. Year one gave a few flashes. I’m interested to see what year two looks like now that he has some experience under his belt.

. He’s bouncy, which creates problems for opposing defenders in the open field, as he can pivot quickly and outrun them on the outside. Grinstead’s speed was on full display while standing out on St. Xavier’s freshman and JV teams in 2025. Varsity reps could come his way this fall as he continues to prove his abilities this summer.

stood out with a physically developed build for his age and the type of athleticism that immediately catches your attention. He moves with impressive fluidity for a young prospect and showed the ability to accelerate quickly when the ball was in his hands. Grinstead flashed sudden explosiveness throughout the day and looked comfortable operating in space, highlighting the athletic tools that make him an intriguing two-way prospect moving forward.

. The former Lyndon Lightning stand out is well-put together in terms of muscle mass and enters high school with pretty good speed. On the field he displays strong contact balance that makes him difficult to bring down in the open field if a defender makes contact on him. Not necessarily a burner, but fast enough to get through the holes opened for him. In theory he would thrive more in a power run scheme, than a zone scheme, but he can do both. This off-season he has worked hard as of late to improve his presence in the passing game. He looks noticeably more comfortable and natural catching passes out of the back field.
