Key metric: Olympic Medal Count

Let me tell you something - this story is a GAME-CHANGER for Team USA's medal hopes! Charlie Volker, a former gridiron warrior turned bobsled dynamo, has been forced to hang up his cleats - or should I say, his sled! - due to a brutal concussion. This is a MASSIVE BLOW to the USA Bobsled squad, folks! Volker was their secret weapon, their fourth-quarter comeback kid, and now they're heading into the Olympic showdown without their star player. It's like losing your quarterback right before the Super Bowl! The U.S. team is going to have to dig deep, show that championship mentality, and find a way to fill this gaping hole in their roster. This is when champions are made, when teams have to rally together and prove they've got what it takes to overcome adversity. I'm telling you right now, all eyes will be on how Team USA responds to this setback as they gear up for their gold medal push in Italy 2026!
