One of the NFL’s brightest offensive minds agrees with the popular opinion that the vast majority of this year’s top quarterback talents are developmental prospects.

Bruce Arians wouldn’t disclose details, for obvious reasons, but the Arizona Cardinals head coach said just one signal-caller is ready to be an NFL starter.

“I’m not going to mention names,” Arians said at this week’s league meetings, according to Pat McManamon of ESPN. “I think one of them is ready to start as a rookie. I think all the rest, there are some really talented arms that need a year of learning how to play the position, especially at this level.”

Arians and the Cardinals are admittedly in the market for a quarterback to groom as Carson Palmer‘s successor.

Their veteran leader has put off retirement to return for at least another year, though, and does so as the unquestioned starter, allowing the Cardinals to focus on long-term upside at the position.

Among those likely in the mix should Arizona go the quarterback route at No. 13 overall are Deshaun Watson, DeShone Kizer, Mitchell Trubisky, and Patrick Mahomes.

Putting off such a selection until Day 2 would bring names like Davis Webb, Brad Kaaya, and Nathan Peterman into the conversation.

Either way, finding a quarterback that can sit and learn behind Palmer could significantly ease the transition period that will follow the 37-year-old’s eventual decision to call it a career.

Palmer struggled through a drop-off in effectiveness last season and took some time to consider his future after completing 61 percent of passes for 4,233 yards, 26 touchdowns, and 14 interceptions.
