When the grenade explodes near the ice truck, the man jumps from his truck. It can clearly be seen (slow-mo) that he loses his cap. After the first cut, he is seen running without his cap. After the second cut, when Crockett arrives with the blanket, the man has his cap back on.
Early on when Archie refers to college "scouts" coming to observe and evaluate his athletic performances during his high school football games, in college they are actually called "recruiters".

After the grenade explosion scene, Lt. Atkins inquires about one of his men hurt in the blast. Tubbs tells him that the man went to "Good Sam" for treatment. Good Sam is short for Good Samaritan, which is a Hospital in West Palm Beach. This hospital is roughly 71 miles away from Miami, it is not a trauma or burn center, and he would've bypassed many geographically closer and better suited hospitals along the way (including Jackson Memorial) to get to Good Sam.
