Kellen Moore was signed immediately after the draft to be the Lions third quarterback, if they keep a third quarterback.

If Moore (Boise State) had a stronger arm, he would have been drafted since he was the winningest quarterback in college football with a record of 50-3.

Here are three reasons the Lions could keep Moore on the 53-man roster.

1. He is never going to throw 65- or 70-yard bombs like Matthew Stafford, but he knows his limits and is generally able to move the chains. He knows what he has to do to move the ball down the field.

2. Moore picked up the offense quickly. During minicamp when he was running the drills, the pace didn’t slow down. Stafford said that’s a good sign for a rookie.

3. During minicamp he completed a high percentage of passes and was able to move the offense down the field. He’s a coach’s son, is smart and is well liked by Scott Linehan, the offensive coordinator.
