Glennon was 4-9, taking over Tampa Bay’s offense after Josh Freeman struggled and subsequently was released.
The third-round draft pick threw for 19 touchdowns and just nine interceptions as a rookie, but also was sacked 40 times while failing to demonstrate he was the team’s clear-cut quarterback of the future.
The signing of Collins, a part-time starter the past six seasons with Cincinnati, upgrades a porous offensive line that needs to do a better job protecting the quarterback.
Like McCown, the 6-foot-7, 315-pound tackle is savoring the chance to show he can flourish as a full-time starter.
“Patience is a virtue,” Collins added. “Now is my time.”
