Considering RGIII's great success with the read option also led to his injury (I realize QBs get injured anyway but for the purposes of this conversation I am assuming that read-option QBs are more exposed to injury than pro-style QBs), will the NFL gradually become a read-option league? I have to admit, marquee DEs were absolutely paralyzed by the Redskin offense (i.e. Demarcus Ware). But won't quarterbacks then have the same shelf-life as running backs because of the constant hits they are exposed to? Will teams have to have three ready QBs to come in at the drop of a hat, run the offense just as effectively and, most importantly, lead as well? Would this transition increase or decrease the crucial role that QBs play in a team's success?
