The lack of yard signs can signal complacency, or the idea you think you’ve already won so there’s no reason to have them.
I think his manager may be wrong on this one.
You have to look like you’re in the game.

In the 2016 Election, Hillary signs littered all of San Antonio including signs with Hillary, Obama & JFK faces on them. I saw 0 Trump signs. Hillary lost cause signs are just litter and car stickers make me not want to drive behind them. So signs might help get you name out, but it can also easily become an annoyance. Conservative signs in front of homes and on cars should be left for the violent Democrats to get bored with.
