As Kellen Moore prepares for his fourth training camp, he is for the first time in the mix to become the Detroit Lions’ No. 2 quarterback. It’s between him and veteran Dan Orlovsky.

Here are five reasons Moore could be promoted to No. 2:

1. He has improved as time goes along. “What we’ve seen from him is kind of what we anticipate when you have a guy that has the talent, anticipation and work habits that he does. He’s improved, he’s gotten better, so it will be a nice battle I think in the fall to kind of see what happens. But I think he’ll be right in the thick of things,’’ coach Jim Caldwell said.
   
   
2. Moore, like the others has a better grasp of the offense that was installed last year. “You know, he has a good understanding of our offense as well. He has some unusual traits and he’s getting better all the time,’’ Caldwell said.
   
   
3. He doesn’t have the arm of Stafford but he can get the ball down field. In the preseason games in 2014 he proved he can move the offense. Yes, it was against second and third-line defenses but he was working with second and third-tier teammates too.
   
   
4. He has zero, zip experience in a regular season NFL game. But, hey, everyone has to start sometime. Preseason games aren’t the same, but it’s close. If he has a good training camp, look for him to be second off the bench instead of third in the preseason contests. Orlovsky does have NFL experience, but hasn’t thrown an NFL pass since he played in one game with Tampa Bay in 2012.
   
   
5. Throughout OTAs and minicamp, he regularly split the reps with the twos with Orlovsky. That was the first sign that something could be brewing.
