1. Tannehill's momentum: Has Dolphins starting quarterback Ryan Tannehill fully turned the corner in Bill Lazor's new offense? It's too early to tell. But last week's 6-for-6 passing performance for 62 yards and a touchdown against the Atlanta Falcons certainly provides reason for optimism. Tannehill played only one series in the preseason opener but carried that momentum into a solid week of practice. He finished training camp on a strong note with several good practices heading into Saturday's game. Now, Tannehill must continue to build off that momentum with a solid outing against Tampa Bay.
2. Will tackling improve? The Dolphins were a poor-tackling defense in 2013. Last week's preseason opener against Atlanta offered more of the same. Therefore, Dolphins head coach Joe Philbin put a major focus on form tackling this week. Philbin hopes those sessions pay dividends and that his defense tackles much better this week, especially when the starters play in the first half. Keep a close eye on Miami's starting linebackers, who must improve this year.
3. Changes in secondary: The Dolphins received bad news just hours before last week's exhibition game when starting safety Reshad Jones was suspended four games for violating the NFL's policy on performance enhancing substances. Jones started anyway against Atlanta, because it was too late for Miami to adjust the secondary. However, the Dolphins made several changes in practice this week by inserting backup Jimmy Wilson into the starting lineup and making Jones a backup. Wilson also had to give up his nickel corner role. Miami is still trying to decide who will take that job. Candidates include starting corner Cortland Finnegan, corner Jamar Taylor and backup safety Michael Thomas.
