According to ESPN's Jeff Legwold, the team's owner described the lackluster 2-5 start as "disappointing" at a fan event in London.
The Broncos were purchased by Penner, the chairman of Walmart and a member of the Walton-Penner family, for $4.65 billion in August.
The Broncos have fallen short of what they were paid for. They average 14.3 points per game and rank bottom in scoring offense. After three embarrassing losses in prime time, they received mockery.
Changes might occur if they drop five straight games to Jacksonville. They are considering sacking Nathaniel Hackett, the team's inexperienced head coach,
and trading numerous players, including Bradley Chubb, a former defensive end who made the Pro Bowl, according to ESPN NFL sources Dan Graziano and Jeremy Fowler.
We still have great expectations, as do our supporters, and we're not where we need to be, according to Penner.
