With Carr moving on to a life after football, the Saints have rookie Tyler Shough, second-year QB Spencer Rattler and Jake Haener headed toward a QB competition. That list of options, however, is missing a veteran signal caller, who could prove of significant value to New Orleans -- even if that player doesn't end up starting Week 1.

After Derek Carr's sudden retirement, the New Orleans Saints are left with three quarterbacks on their active roster. And according to new head coach Kellen Moore, they will each get a chance to compete for the starting role in Carr's absence.

Even though Carr's decision to retirement came as a shock to the NFL world, the Saints weren't left in the dark about it.
