The comment below was so in depth and detailed that it impressed those who saw it so much that I felt it needed to be a stand-alone article to let the many fans, as well as his detractors, what the definition of a "Franchise Quarterback" is, and why the Ravens were so smart to ink this guy to a long-term deal, regardless of the cost. Enjoy!
