According to the Palm Beach Post, rookie Ryan Tannehill is "not in the running" for the Dolphins' starting quarterback job heading to training camp.
Beat writer Brian Biggane attributes Tannehill lagging behind David Garrard and Matt Moore to "untimely mistakes, particularly when throwing into traffic." It should be noted that his pre-draft scouting report had a similar criticism. Biggane expects Tannehill to "continue his apprenticeship as the No. 3 guy." The Week 1 job will likely come down to Garrard and Moore. It is mildly concerning that Tannehill did not make a spring run up the depth chart considering his knowledge of OC Mike Sherman's offense.

Personally I see the "throwing in to traffic" issue as having a lot to do with him adjusting to the speed of the game. Absolutely no reason to be legitimately concerned yet.
