Griffin went undrafted in 2013 and signed with the Saints as an underdrafted free agent shortly after. He stayed with the Saints until being waived by the team ahead of the 2015 season, and never played one snap for them.
Griffin then left the NFL, only throwing for 2 completions on 4 attempts in his career, and joined the Italian Football League back in November.
Now, Griffin is returning to the NFL, but will be coaching on the Bears and will be working closely with the QBs and WRs.
