Kiz: If pent-up frustration in Broncos Country has a face, it’s that persecuted look on the mug of offensive tackle Garett Bolles when he’s penalized for holding. Every fan in the stadium knows his number, for all the wrong reasons. “The hard thing is that Garett is under the microscope,” said John Elway, who drafted Bolles in the first round. “He’s under the microscope, and any time (the officials) say ‘72,’ it brings down the whole stadium.” So I gotta ask: The Broncos can’t possibly bring Bolles back as a starter next season, can they?
