Miami Dolphins teammate impressed by Brent Grimes progress

Miami Dolphins tight end Charles Clay has said that the team have been impressed with Brent Grimes's progress during this off-season.

The cornerback, who signed a one-year contract with the AFC East side in April, missed the majority of last season for the Atlanta Falcons with a torn Achilles.

Clay told the South Florida Sun Sentinel: "Every day Brent Grimes does something where we're like, 'that guy is a freak athletically'. Blows my mind. He has the quarterbacks saying, 'I'm not going to throw to that guy'."

Grimes spent six seasons with the Falcons before joining the Dolphins.
