The tweet -- once again from the data divers at profootballfocus.com -- made it simple: In the 100 targets they counted for Larry Fitzgerald in 2014, the Cardinals did not throw one interception. Not from Carson Palmer, or Drew Stanton, or Ryan Lindley or Logan Thomas. That, PFF said, meant Fitz was the safest receiver to throw to in the NFL last season.

(Yes, I know Lindley's backbreaking playoff red-zone interception in Carolina was supposed to go to Fitz, but all stats usually are regular season only unless noted.)

In itself, an interesting stat. But it got me thinking. In 2013, the Cardinals definitely threw an interception or two throwing to Fitzgerald -- or Palmer did, since he took every 2013 snap. It was a big deal at the time, with Bruce Arians trying to teach a) his offense to a new QB and new wide receivers and b) a new position to Fitzgerald. More than once it was mentioned that Palmer was trying too hard to force the ball to Fitzgerald, something Palmer acknowledged he learned from once 2014 came around.

So I asked PFF what the Fitzgerald INT number was for 2013. It turns out Palmer had a whopping seven interceptions when targeting Fitzgerald in 2013. Now, there is no breakdown with that. It's impossible to know who might have been at fault, whether the defender made a great play or if the pass rush caused a problem. But it does show the evolution of Arians' offense and how much more comfortable Palmer and Fitz were within it. We have touched on the subject of the improvement of Palmer working with Fitz before. The numbers seem to back it up.
