Coach Dave Wannstedt made the point that Fiedler hadn't faced a live blitz until the Dolphins opened the preseason Monday night at Tampa Bay.
The need to get Fiedler some action was the reason Wannstedt left him in the game until late in the second quarter.
"It's obvious that Jay needs a lot of work," Wannstedt said. "He's behind, and we're fortunate that we have three weeks before we play to get that done.
"The throws that he made were just off. There's no simple way to explain it. He just wasn't very accurate tonight."
Wannstedt made the point that the passes on which Fiedler was intercepted are throws that he makes all the time.
But he wasn't making them tonight.
And it wasn't just the interceptions. Fiedler also was off on some other throws, including an underthrow down the sideline after Chris Chambers had beaten the defensive back.
"I just have to get my feet set," Fiedler said. "I threw a couple off balance. I just have to get my rhythm back while I'm out on the field. Two of (the) interceptions were just bad throws where I wasn't set to make the throw."
No one on the Dolphins is panicking about Fiedler, and it's too soon to do it.
But it's clear he needs to be much better when the Dolphins play again, Aug. 24 at Houston.
