Grading the five rookie QBs

Robert Griffin III had a great debut. Things didn't go as well for Ryan Tannehill and Brandon Weeden. US Presswire

For the first time in NFL history, five teams started a rookie quarterback in Week 1. Four of those five QBs were first-round picks, including the first and second overall selections. As expected, there were plenty of struggles, but also quite a few good signs of things to come. Andrew Luck looked good, Russell Wilson was average and Robert Griffin III was terrific. On a negative note, it sure looks like it will be a very long rookie year for Ryan Tannehill and Brandon Weeden.
