Under constant pressure, Ryan Tannehill kept backpedaling, trying to buy more time so he could improve his accuracy.
This wasn't the Miami Dolphins' revamped offense at work. This was celebrity tennis at the Sony Open.
Tannehill, who has played the game only a handful of times, took part in a doubles match Thursday with NFL offensive lineman Bryant McKinnie and two of the world's best doubles players, Nadia Petrova and Katarina Srebotnik.
''I'm not going to be going down to the local club and beating anyone,'' Tannehill said. ''But it's fun to do something different.''
The match gave Tannehill a break from offseason work as he prepares for his second season with the Dolphins, who have been busy trying to upgrade his supporting cast. This month they signed Mike Wallace, the top pass-catcher in free agency, and wideout Brandon Gibson and tight end Dustin Keller. They also re-signed wideout Brian Hartline.
That means big changes ...
