Grbac replaced Steve Bono as the Chiefs starter in 1997.
He orchestrated a Monday Night Football comeback in Week Two against the Oakland Raiders.
Despite trailing by two touchdowns late in the second half, he rallied the Chiefs by directing a six-play, 80-yard touchdown drive without the benefit of a single time-out, culminating that comeback with a 32-yard game-winner to Andre Rison with 0:03 remaining to seal a 28–27 Chiefs win.

In the 1997 season Grbac led the Chiefs to their fourth AFC West Division championship, as the team finished the year with six consecutive victories, a first in team history.
The 1997 season was also the beginning of a quarterback controversy, when Grbac started the first nine games and suffered an injury, leading to Rich Gannon's substitution for the next six games.
Grbac would return in the team's season finale.
Gannon won five consecutive starts down the stretch to help the Chiefs earn home-field advantage with a 13–3 record.
Grbac was an excellent quarterback, and a talented thrower, while Gannon was an aggressive leader who demanded the most of his players.
Grbac was selected by coach Marty Schottenheimer to start the team's playoff game against the Denver Broncos, a game which the Chiefs would lose 14–10.
Chiefs fans were divided over whether Gannon or Grbac should lead the team.
Eventually Grbac was chosen to remain the Chiefs starting quarterback, Gannon was let go and signed with the Raiders in 1999.
