Brunt has been restricted to just two starts and three substitute appearances in the Barclays Premier League following an influx of new midfield signings in the summer.
Downing told the WBA website: "He's got high pass-rates, he's got assists, he's a consummate pro, he leads the group and has a high regard within the group, and he is experienced in terms of the position he plays.
"I suppose the formation, with the two holding midfielders, and us being more attack-minded in the wide areas, has that affected people's perception?
"I don't know whether they want to see wingers who will fly past somebody?
"Chris isn't that, he's an influence in the middle of the park who keeps things moving."
