Kellen Moore took some time to acclimate to the NFL, but he developed enough to convince the Detroit Lions to retain him on their 53-man roster. By earning a spot on the active roster, Moore bought himself some more time to develop, and he should eventually develop into a successful backup in the NFL.
A fair comparison for Moore would be Brad Johnson. Johnson never had elite physical tools, but his savvy and accuracy were enough to keep him employed for years.
The NFL has changed since Johnson was a starter, making it harder than ever for a weak-armed quarterback to be successful.
That means that Moore will likely be relegated to a backup role throughout his career, but that is by no means a death sentence for the young man.
Moore could develop into the long-term backup in Detroit. Backing up the oft-injured Matthew Stafford would guarantee Moore some action throughout his career, while also ensuring that he would have some solid weapons around him.
This is a perfect situation for Moore, and Moore is also a perfect fit for the Lions. The Lions have their backup right now in Shaun Hill, but Hill is aging and probably won't be in the NFL for more than a few more years.
That will give Moore plenty of time to develop, which in turn will give him an opportunity to eventually be the primary backup in Detroit.
Moore would be the perfect complement to Stafford and would grant the Lions security at quarterback for years to come. Moore's intelligence would help the Lions and Stafford immensely, giving Detroit a pseudo-coach to help Stafford continue to develop.
Make no mistake: Moore has legitimately earned his spot on the roster. And in doing so, he has guaranteed himself a nice, long career as a backup quarterback.
