The Miami Dolphins devoted a significant portion of Thursday's practice toward preparing for their second preseason game Saturday at the Tampa Bay Buccaneers, whose strong secondary should face the preseason debut of wide receiver Mike Wallace.

Much of the buzz throughout the offseason centered on new coordinator Bill Lazor's up-tempo offense, and the potential explosive play-making ability with Wallace being put in motion to create mismatches. But Wallace has been catching more passes from the JUGS machine of late than quarterback Ryan Tannehill as he recovers from a hamstring injury.

Wallace said he is "totally comfortable" with the offense, while acknowledging the system is still being installed with less than a month before the regular-season opener. He does expect to make his preseason debut Saturday and begin adjusting to the speed of live game action and working on his timing with Tannehill.

"Not so much as the plays, just the rapid fire of the offense you need to go, so you can have your endurance up," Wallace said of the benefits to getting into a preseason game. "Just two days off in this offense will have you gassed. You have to keep going and keep building your endurance every single day. So I definitely need to go out there and get some plays in."

Rather than staying on one side of the field this season, Wallace will often be on the move in search of mismatches. The goal is to spring Wallace for more of the big plays that were his trademark with the Pittsburgh Steelers but largely disappeared during his first season with Miami.
