Mills was one of the more intriguing players in the draft because of his talent yet minimal playing time in his college career.
The Georgia native was a 5-star recruit out of high school and considered the No. 1 pro-style quarterback in the 2017 class, per 247Sports' composite rankings. At 6'4", 217 pounds with a strong arm and impressive accuracy, it's easy to see the upside as a passer.
Running the 40-yard dash in 4.58 seconds at his pro day also showed Mills has good athleticism at the position.
The questions come from a lack of experience, with him making just 11 starts at Stanford. He took over the role late in 2019 while his 2020 season was limited to just five games because of COVID-19 protocols.
Mills finished the past year with 1,508 passing yards, seven touchdowns and three interceptions, bringing his career totals to 18 passing touchdowns and eight interceptions. For comparison, Mac Jones had 41 passing touchdowns just that year at Alabama while throwing only four picks.
There were also few opportunities for Mills to use his legs, with him scoring three rushing touchdowns but only managing 37 rushing yards in 2020.
It makes him a high-risk prospect without much proven production, but there's excitement about what he can bring in the future.
The limited playing time in college will likely lead to a slow transition in the NFL, and the Texans will need to remain patient
Mills still has the potential to move up the depth chart down the line and be a reliable starter in future seasons.
