Steve Smith’s battle with Aqib Talib was the best drama on television Monday, complete with big plays, hints of violence and perhaps the best post-game trash talk of the season. “Ice up, son. Ice up,” Smith instructed Talib after his Panthers beat the Patriots, both on the scoreboard and physically, in a 12-round, knockdown bout. Fast-forward a week, and if Smith snarled the same junk to his likely opponent this coming Sunday — Brent Grimes — he’d probably get a laugh in response. For while Talib tries to cover with swagger and intimidation, that’s simply not Grimes’ style. “I really don’t get into it like that,” Grimes said with a chuckle. “[Smith is] known for getting into stuff. He’s high-strung, obviously. He’s competitive. He gets excited, extremely excited, when he makes plays.” Through 11 weeks of the NFL season, Grimes has shown that happy-go-lucky can work just as well — if not better — than fire-and-brimstone. Simply put, he just might be the lockdown corner the Dolphins have searched for since the days of Patrick Surtain and Sam Madison. The scouting website Pro Football Focus ranks Grimes as the third-best corner in the league. He has three interceptions. He hasn’t allowed a touchdown all season. Quarterbacks have a rating of just 62.4 when throwing to his coverage area. And he has done it without a lot of help. Fellow Dolphins corner Dimitri Patterson estimates the coaches ask Grimes to play man-to-man between 80 and 90 percent of the time — a figure Grimes didn’t dispute.
