If you ever wondered how Brock Purdy would perform when shorn of all his starting offensive weapons and playing behind an offensive line featuring just two starters from last season, you got your answer in Sunday's preseason game with the New Orleans Saints.

Purdy played three series in the 49ers' win over the Saints, and he spent most of them running away from pressure as the makeshift O-Line failed to give him consistent protection.

The Niners' starting quarterback finished two of six for 11 yards, took several hits and was fortunate not to be intercepted.

San Francisco's offense obviously is unlikely to be so undermanned come the regular season, but Purdy and the 49er attack have had to deal with a host of absences during training camp.

Indeed, the offense has been beset by injuries, while the hold-in of Brandon Aiyuk and the holdout of Trent Williams have kept two of the 49ers' best players off the practice field.

With the likes of Aiyuk, Williams and Christian McCaffrey (calf) being conspicuous by their respective absences, Purdy was asked following his frustrating preseason showing if the offense could be clicking by the time it faces the New York Jets' vaunted defense on Monday Night Football in Week 1.

"Obviously I think we've got to take it day-by-day and get guys healthy, that's the first thing," Purdy said.

"I can't just sit up here and tell everybody that we're going to be perfect and we're going to look a hundred percent come game one. Obviously everyone's different in terms of their bodies being healthy. 

"But from the history that we have with guys rehabbing and getting healthy and our medical staff, they get guys ready and I think come Week 1 we'll have a good majority of us ready to roll. 

"So I'm pretty confident in that. And obviously the coaches are going to do some good scheming and stuff. I think we will hit the ground running."

It will take more than just star players returning to the fray for the 49ers to perform to the standard Purdy anticipates for Week 1. He will need to operate at a higher level than he did during his brief cameo against New Orleans, in which he was guilty of wasting some opportunities to hit open receivers. 

Still, Purdy's brief history in the league suggests that, when the games start to matter, he will rise to the challenge. Provided he has at least some of his premier weapons out there, the smart money is on an improvement in standard from the starting quarterback and the presence of an All-Star supporting cast resulting in the 49er offense meeting his expectations.
