Here are several observations for Miami:
The Dolphins' passing game finally woke up in the preseason thanks to new No. 1 receiver Mike Wallace. He caught three passes for 58 yards and a touchdown from quarterback Ryan Tannehill, and all of it came on the third drive. Wallace showed the full range of playmaking by catching a 16-yard pass for a first down, a 33-yard catch over the top and a 9-yard touchdown reception by finding a hole in the zone. Dolphins fans were prematurely antsy about Tannehill not connecting with Wallace up to this point. The pair had a good week of practice, and it showed in the game.
Tannehill also had his best game of the preseason. Tannehill was 10-of-15 passing for 141 yards and the touchdown pass to Wallace. It’s also worth noting that two of Tannehill’s five incompletions were drops by running back Lamar Miller and Brian Hartline. Overall, Tannehill was poised and made a nice range of throws against a tough Houston defense. Perhaps this performance will provide some momentum for Tannehill in the rest of the preseason.
The worse news of the night for Miami was the potential knee injury to starting tight end Dustin Keller. He made a second-quarter reception and took a shot directly on his right knee as he was coming down. Keller's leg hyper-extended and he clutched his knee in pain. Keller was later carted off the field and couldn’t put weight on his right leg, which are not good signs. Keller's injury appears to be significant, and the Dolphins most likely will have to rely on young tight ends like Dion Sims and Michael Egnew for a while.
Miami’s offense played well overall, but it was a rough night for Dolphins right guard Josh Samuda. He had another opportunity to prove that he can play with the starters and struggled mightily against Houston’s talented defensive line. Samuda was beat easily by Texans defensive lineman Antonio Smith twice on big plays. Smith registered a sack and a tackle for loss on Miller in the first half. Samuda also was abused by Texans star J.J. Watt on a third-down screen pass. Samuda did not step up to the high-level competition Saturday night, which is telling. Miami’s best option at guard would be a healthy John Jerry.
New Dolphins corner Brent Grimes made his presence felt. Grimes has been one of the most consistent players in Miami’s training camp, and he got his first interception with an athletic play to pick off Houston quarterback Matt Schaub. Grimes read the route by Texans rookie receiver DeAndre Hopkins and broke on the ball as it was released. Grimes jumped in front of Hopkins to take the ball away, which is a play you didn’t see often from Miami’s defense last year.
Dolphins rookie corner Will Davis has made some headlines lately for his play. But Davis was beat for a touchdown on fourth down when Houston receiver Lestar Jean made a double move. Davis also was beat for a 16-yard reception in the first half in man-to-man coverage. It was a good learning experience for Davis.
Miami’s backup offensive line is not very good – and second-string quarterback Matt Moore found that out the hard way. Moore played the entire second half and was pressured throughout. He was sacked four times in two quarters of work and pressured several more times. The Dolphins are looking offensive linemen to provide depth. No one beyond the starters stood out Saturday.
Miami has two preseason games remaining. The Dolphins will be off Sunday and then prepare for their fourth preseason game at home against the Tampa Bay Buccaneers.
