FLOWERY BRANCH — If the Atlanta Falcons are going to get back on track Monday night against the New York Jets, they'll have to do it with an offensive line that has not yet proven to be ready for prime time. Left tackle Sam Baker did not practice Thursday is likely to miss his second game, leaving Atlanta with two tackles — Lamar Holmes on the left and Jeremy Trueblood on the right — who were not expected to be starters. The Falcons (1-3) have fallen short of preseason expectations and most of their problems have been on offense, especially in the red zone where blocking issues are magnified.
