Matt Maiocco of CSNBayArea.com believes rookie B.J.Daniels will challenge Scott Tolzien for the 49ers third quarterback spot.
Daniels, a seventh-round draft pick from South Florida, might have an edge over Tolzien due to his versatility. Daniels has good running ability and a strong arm. He could be active as the No. 3 quarterback because of his ability to play different positions and contribute on special teams. Tolzien is a heady quarterback who has served as the third quarterback in both of his first two season. He has suited up for three games but has yet to play in a regular-season game.
