Wearing jersey number 3, Cameron started his first game completing 12 of 14 for 179 yards and 3 touchdowns, leading the team to rout the Hurricanes 93–0 on Sunday, May 4, 2014, in the preliminary round of the Pearl Bowl preseason tournament at Kawasaki Fujimi Stadium.[7]

The Frontiers advanced to the championship game against the Obic Seagulls on June 23 in the Tokyo Dome.[9]
In the Pearl Bowl final, Cameron struggled against the Obic Seagulls defense led by American defensive ends Kevin Jackson and BJ Beatty Jr. He completed 17 out of 32 for 172 yards with 1 touchdown and 1 interception. He was also sacked twice as the Obic Seagulls executed a comeback drive during the last 2:03 of regulation which ended with a 19-yard touchdown pass from Obic QB Shun Sugawara to RB Takuya Furutani on the final play of the game to tie the score at 28–28. After missing the PAT, the game went into overtime with both teams scoring field goals on their possessions. During the second overtime period, Fujitsu failed to get a first down and settled for a field goal. Obic moved to the 8-yard line in three plays, then Sugawara took it in himself on a quarterback draw, diving at the goal line to lift the Seagulls to a 37–34 2-overtime victory over the Fujitsu Frontiers.[10]
During the 1st Stage, Cameron was second in the league behind IBM Big Blue's Kevin Craft for passing yards throwing for 1,108 yards with a 66.1 completion percentage, 18 touchdowns and 2 interceptions.

Cameron threw for an X-League career-high 445 yards with 4 touchdowns and 1 interception to lead the Frontiers to a 48–28 victory. The victory alongside the Frontier's previous win over the Central Division 3rd-place Asahi Beer Silver Star assured them a spot in the Final Stage with their next opponent standing in their way before the Japan X Bowl being the Obic Seagulls.[11] Fujitsu beat the Obic Seagulls 27–14 ending the Seagulls' four-year championship run. Cameron completed 28 of 40 passes for 280 yards and two touchdowns while scoring another rushing to guide his team to its first win over the Seagulls in the fall season since 2007. The Frontiers advanced to the Japan X Bowl for the first time in franchise history to take on IBM Big Blue in the Tokyo Dome on December 15 with both teams competing for their first league title.[12]
Cameron started for the Frontiers during the Japan X Bowl against the IBM Big Blue. He completed 13 out of 21 passes for 115 yards during the first half before an injury forced him to sit out the remainder of the game. Second-string quarterback Keiya Hiramoto filled in Cameron's spot in the 2nd half as the Frontiers routed the Big Blue 44–10 for their first X League title in franchise history.[13] Cameron sat out during the Rice bowl national championship game on January 3, 2015, that resulted in a comeback 33–24 victory by the Frontiers over the collegiate champion Kwansei Gakuin University Fighters.
Cameron finished the 2014 season for the Frontiers accumulating 3,045 passing yards with a 67.1 completion percentage rate, 33 touchdowns and 6 interceptions.

On October 3, 2015, Cameron completed 26 of 39 passes for 294 yards and two touchdowns while the Fujitsu defense limited Nojima Sagamihara's new import Quarterback Benjamin Anderson to just 144 yards total offense en route to a 37–10 victory at Fujitsu Stadium Kawasaki. This would bring the Frontiers to overall record to 4–0 and a match up against rival team the Obic Seagulls for the Eastern Division title.[14]
