Following the 2013 NFL Draft, the Detroit Lions signed Western Michigan quarterback Alex Carder as an undrafted free agent. The move was done to add an arm for the Lions' rookie minicamp, as well as to give Kellen Moore some competition for the third quarterback spot in training camp.
Interestingly enough, the fourth quarterback spot on the Lions' roster almost went to Vanderbilt quarterback Jordan Rodgers, who is the brother of Green Bay Packers quarterback Aaron Rodgers. The Lions were one of two teams that Rodgers was considering after going undrafted. In the end, he opted to sign with the Jacksonville Jaguars since their roster presents a better opportunity to make the team. From FOXSportsWisconsin.com (via MLive):
"We were focused on those two teams because of the personnel at the position, but (the Jaguars) were the best opportunity," Jordan said. "They provide one of the better opportunities you can ask for as a free-agent quarterback. There's only two (quarterbacks) on the roster, and most teams have three or maybe four.
The top two spots are set on the quarterback depth chart for the Lions (Matthew Stafford and Shaun Hill), and Moore is the favorite to retain the third spot after spending a year on the 53-man roster. In that regard, the Jaguars certainly present a better chance to make the team, as their quarterback situation is far from settled. With the Lions, the only question at QB is if Carder will be able to push Moore for the third and final spot on the roster at the position.
