What happened: Miami signed quarterback Mark Gronowski and inside linebacker Cam Riley. The team also placed guard/tackle Jamaree Salyer on injured reserve and waived/injured cornerback Ethan Robinson.

Why it matters: The moves reshuffle Miami's roster at three positions in one transaction batch, with Salyer's IR stint costing the club a versatile line piece capable of playing guard or tackle.

What to watch: Watch how Gronowski and Riley factor into practice reps as Miami's roster continues to take shape.
