Veteran defensive tackle Isaac Sopoaga has practiced with the New England Patriots each of the past three days since being acquired in a trade from the Eagles, and coach Bill Belichick said Friday that there is a good chance Sopoaga will play Sunday against the Steelers. “We have a couple more days to clean up a few things, but if he continues to progress through the week, I don’t think there’s any reason why he shouldn’t be ready to play,” Belichick said. Belichick made the point that acquiring Sopoaga at this point of the season is different from signing a free-agent, as he’s in “football shape” from having played in every game (39 percent of the Eagles’ defensive snaps). “He’s in good condition, his reactions are what you’d expect them to be,” Belichick noted. “He just has to get familiar with our terminology and some of the way we play certain blocks and what his responsibilities are on blitzes and that kind of thing. He’s a smart guy and he obviously has a lot of experience.” From a big-picture standpoint, Belichick was asked what he remembers about Sopoaga from the 2004 draft. Sopoaga, who played at Hawaii, had visited Gillette Stadium and was a prospect the team had interest in selecting before he went in the fourth round (49ers).
