Training camps across the NFL are heating up as teams don full pads and rookies get their chance to shine. The Dallas Cowboys saw notable performances from rookies like Marshawn Kneeland, who is stepping up due to Sam Williams' injury, and the return of cornerback Trevon Diggs from injury. In Philadelphia, first-round pick Quinyon Mitchell has impressed in his new role as slot cornerback, showing his competitive edge against star receiver A.J. Brown. Additionally, the Eagles face a setback with Cooper DeJean sidelined for three weeks due to a hamstring injury. Meanwhile, the Colts' rookie pass-rusher Latu is making waves with his standout performance against the starting offensive line. These developments are crucial as teams prepare for the preseason and make final roster decisions.
