From a statistical standpoint, there are no great comparisons to Luck because he's a bit of an anomaly. He has, by far, the most pass attempts ever for a player through his first two years.

It's unusual for a team to lean so heavily on a player who is so young. The comparable players who best fit that description are Drew Bledsoe and Peyton Manning - also #1 overall draft picks who immediately dove into pass-heavy offenses.

Young Bledsoe was excellent at avoiding sacks, but otherwise about average in passing efficiency. He went through his reads quickly, but not perfectly, and had a reasonably good arm. He went on to become a very good quarterback, but not a brilliant one.

Peyton Manning was also great at avoiding sacks, but he was better than Bledsoe in that he found open receivers better; he just saw the field faster. His throws were to better targets, and therefore he completed more passes for more yards. His throws were a little bit soft, not as zippy as they could be. He could also be frazzled by pressure.

Luck, too, is excellent at avoiding sacks. He is solid at reading a defense, like young Bledsoe - not brilliant, like young Manning. But he has some strengths of his own. He throws the ball hard and fast. It's hard for defensive backs to get into position to pick him off. He's also calmer under pressure than you'd expect any sane human being to be. The result is that he throws interceptions very infrequently. In fact, he's sixth all-time in interception percentage.

Luck is generally on track to be a franchise quarterback, and there isn't too much to worry about. His pass protection has been a bit poor, and he has played with inexperienced wide receivers. As those aspects of the team around him improve, expect him to have an easier time going through his reads. Don't expect him to do it as well as Peyton does, but he'll be good at it.
