Normally, yes but I don't consider a throw like that to Fitz dangerous. There aren't many Dbs in the league who are going to come down with the ball over Fitz.
He's having a monster game. I love when both guys are healthy. If the D tries to double one then the other kills them. Especially when Fitz is out wide and Boldin in the slot on that side. You can only put so many defenders on one half of the field.
