The first month of the season is officially in the books, and Michigan State fans are thrilled with what they’ve seen so far from junior quarterback Aidan Chiles.

The second-year starter for the green and white has been one of the most improved players on the team, completely flipping his touchdown-to-interception ratio through the first four games this year compared to last season. He has nine touchdown passes to just one pick and a year ago at this time, he had four touchdowns to seven interceptions.

Chiles has improved in every aspect from deep-ball accuracy to decision-making to overall accuracy, he’s not making the poor decisions he was a year ago.

The Oregon State transfer has been one of the best quarterbacks in the Big Ten this season, passing for just shy of 900 yards with nine picks and improving his accuracy by about 10 whole points from a year ago. He’s also reportedly one of the 15 most efficient quarterbacks in the country through five weeks.

As you can see, Chiles is ranked 15th nationally in EPA per dropback which translates to Estimated Points Added per every dropback a quarterback takes. Obviously the higher number, the better. Anything positive shows that a quarterback is playing well, and Chiles has the 15th-best number in the nation at 0.55 EPA/dropback.

Yet another favorable metric for the talented dual-threat from California. He has now improved his accuracy, touchdown-to-turnover ratio, and overall decision-making and comfortability in the pocket. He might just be the most improved players in the Big Ten so far.
