Sebastian Vollmer is the starting RT and has always been on the roster. I believe you’re referring to DT Joe Vellano, who also made the 53-man roster, as he was never cut/waived/released by New England after training camp and pre-season. Therefore, I'm pretty sure Collie took Wilfork's spot. From the Mormon publication, “Deseret Newsâ€...
Think of the drastic change in “team culture†in New England compared to Collie’s former destination…The Bug-Eyed Psychopathic Wigger’s San Francisco Hell-Hole. From “USA Todayâ€â€¦
I truly hope the best for Collie, a young family man with two young children. Even if this doesn’t prove to be a “new beginning†to the second half of his career, at least he’s being given a chance to shine in the fairest possible offensive environment. At this time three seasons ago, Collie was having the best campaign of any receiver in football and looked entirely uncoverable before sustaining his first ghastly concussion. If only Pierre Garcon had been playing in the slot that day.
FYI, I believe I solved the “mystery†of Joe Vellano, who looks like a white Italian at times, and a Mexican other times. I found this photo of his father, but the only photo of his mother is inconclusive…
CAPTION: "White" Joe
CAPTION: "Mexican" Joe
Regardless, he certainly passes the eye test in uniform...
