"I want to create the most competitive atmosphere that I possibly can," Westhoff said. "Josh Brown is the best candidate to do that with. We want to have a viable battle here to see who's going to win our job and to get the best possible guy that we can put on the field."
Folk, a five-year NFL veteran, made 19 of his 25 field-goal attempts last season. Folk has made 113 of 145 field-goal attempts in his career.
Brown was released by the St. Louis Rams on May 1 after making 21 of 28 field goal attempts last season. But Brown has hit at a clip better than 80 percent in his career, connecting on 220 of 272 attempts.
"Sometimes you just go through some ups and downs," Westhoff said of Brown. "He had a lot of really good years. He fell off a little. I spent a lot of time talking to him about it. I have a very good handle on some of the things that took place and why he wasn't as efficient as he had been. Just issues ... a culmination of things. I feel very confident that that's not a big deal at all."
