Pre-draft Prior to the
2007 NFL draft, Davila was projected to be undrafted by NFLDraftScout.com. He was rated as the 60th-best quarterback in the draft. Davila was not invited to the 2007
NFL Scouting Combine in Indianapolis. {{nfl predraft After going undrafted, Davila attended rookie
minicamp on a tryout basis with the
Cleveland Browns but was not signed. He participated in the
All American Football League combine in September 2007.
Spokane Shock After sitting out the 2007 season, Davila signed with the
Spokane Shock of
af2 for their 2008 season. Davila had a terrific first season of
arena football, as he threw for a franchise-record 2,935 yards and 66 touchdowns, while leading the Shock to a 15–1 regular season record, and a berth in
ArenaCup IX. The Shock lost the ArenaCup to the
Tennessee Valley Vipers 55–56. With Davila's stellar season, he received multiple
Arena Football League (AFL) offers, but re-signed with the Shock for 2009 after the AFL folded.
Arizona Rattlers 2010 With the Shock moving into the newly reformed AFL in 2010, and Davila a
free agent,
Arizona Rattlers head coach,
Kevin Guy, convinced Davila to sign with the Rattlers, rather than re-signing with the Shock, by telling Davila that the Rattlers would "win a lot of football games." He led the Rattlers to their 3rd consecutive ArenaBowl appearance. During
ArenaBowl XXVI, Davila threw 6 touchdown passes, hitting game MVP,
Rod Windsor, 10 times (50% of Davila's completions). The Rattlers defeated the Philadelphia Soul again 48–39, and became the first squad since the 1995 and 96
Tampa Bay Storm, to repeat as back-to-back Arenabowl Champions. The Rattlers also became the first team in AFL history to repeat as champions the following year against the same opponent.
2014 In 2014, Davila led the Rattlers to a 15–3 regular season record. He threw for 4,778 yards and 127 touchdowns, completing 66.5% of his passes, and throwing only 11 interceptions, en route to a fourth consecutive appearance in the ArenaBowl. In
ArenaBowl XXVII, Davila threw eight touchdowns, went 19-for-24 for 237 yards, and threw only one interception in their 72–32 rout of the American Conference champion
Cleveland Gladiators. This victory made the Rattlers only the second team to win three consecutive ArenaBowls, and earned Davila the Russell Athletic Offensive Player of the Game award, as well as his second ArenaBowl MVP award.
2015 In 2015, the Rattlers finished at 14–4 with two of their losses coming at the hands of the
San Jose SaberCats. Davila suffered a lower body injury in week 5 against the
Los Angeles Kiss and missed the next four games. Back-ups
B. J. Coleman and
Shane Boyd filled the void at quarterback by splitting the starts and carrying the Snakes to a 3–1 record until Davila's return. Despite this setback, Arizona managed to win their fifth consecutive division title. In the playoffs the Rattlers defeated the visiting
Spokane Shock 72–41 in the opening round. It set the stage for a postseason match-up with the SaberCats for the fourth straight season. It was also the 2nd straight season the two teams met in the Western Conference Championship game. Only this time, San Jose hosted the Rattlers due to a better regular season record of 17–1. The game was a back and forth affair until the last minute. Davila made a touchdown pass with 40 seconds left in the game to put the Rattlers up 67–63, but the SaberCats managed a late touchdown with 8 seconds remaining to pull off the 70–67 victory. As the new Western Conference champions, San Jose advanced to
ArenaBowl XXVIII eliminating Davila and the Rattlers from contending for a fourth straight championship or appearing in a fifth straight championship game.
2016 In 2016, the Rattlers finished with a 13–3 record as Davila threw for 4,198 yards and 110 touchdowns. Entering the postseason as the AFL's top ranked seed, the Rattlers faced the
Portland Steel in their opening round of the playoffs. Arizona defeated the Steel 84–40 and set a record for most points scored in franchise history. The win advanced Davila and company to their 6th consecutive National Conference championship game. Together, they faced off with the
Cleveland Gladiators, who had managed to upset the
Los Angeles Kiss on the road 56–52, the previous week. In the game, Davila completed 20 of his 27 passes for 222 yards and seven touchdowns. Arizona's defense forced Cleveland to commit five turnovers, only allowing 41 points. Cleveland's quarterback
Arvell Nelson threw several errant passes and two costly interceptions. The Rattlers beat the Gladiators 82–41, en route to their 5th National Conference Championship and a spot in
ArenaBowl XXIX. Davila was named the AFL MVP for the third time in his career in 2016. Arizona lost ArenaBowl XXIX to the Philadelphia Soul by a score of 56–42. The Rattlers moved to the
Indoor Football League after the 2016 season.
Washington Valor On March 19, 2018, Davila was assigned to the
Washington Valor of the AFL. He suffered a career-ending neck injury on April 28 in a game against the Philadelphia Soul. He dislocated his neck and broke his
cervical spine, causing him to spend 18 hours in traction. On July 28, 2018, the Valor defeated the
Baltimore Brigade by a score of 69–55 to win
ArenaBowl XXXI in Davila's absence. On March 30, 2025, Davila was inducted into the
Arizona Rattlers Ring of Honor before their season opener. ==Career statistics==
