CHESTNUT HILL – The boos cascaded down from the bleachers in the second quarter at Alumni Stadium on Saturday when Boston College quarterback Chris Crane was 1-for-5 for one yard and an interception.The performance had most of the 41,000-plus in attendance calling for head coach Jeff Jagodzinski to pull the senior in favor of redshirt freshman Dominique Davis, who did in fact play twice in the first half.But after a first-half performance that was, for lack of a better term, lethargic, the Eagles and offensive coordinator Steve Logan resisted the temptation to let Davis have the stage, instead deciding to turn their senior loose.What resulted was 31 unanswered points as the Eagles overcame a 7-3 halftime deficit to blast Central Florida, 34-7, and improve to 2-1 on the season.”It was a tale of two halves,” Jagodzinski said. “The coaches did a great job of adjusting. Steve came down at the half and we decided to let Chris go.”With the reins finally unshackled, Crane played a lot like his predecessor, Matt Ryan. After completing just 6-of-14 passes for 45 yards in the opening half, Crane finished the game 16-of-34 for 207 yards and a touchdown. He also rushed for two more critical scores in the third quarter when the Eagles assumed control.”The defense couldn’t play any better,” Crane said about the Eagles’ first-half struggles. “We knew that it was all on us. And we went out and said that we can move the ball and just go out, have fun and do it.”Evidently, Crane liked what Logan told him on the headset on the Eagle bench late in the first half.Jeff Smith got the momentum change started when he returned the second-half kick 56 yards to the Knights’ 41. A holding penalty on UCF moved the ball to the 31 before Crane, who was now working from the shotgun with four wideouts, threw a strike to Justin Jarvis for 12.A six-yard completion to Rich Gunnell along the sideline was followed by an eight-yard run from true freshman Montel Harris (13 carries, 113 yards) that got BC to the five. Two plays later, Crane scrambled right on third and goal from the two and found a lane to the goal line to give the Eagles a 10-7 lead.”They had a good game plan against us, but we definitely realized at the half that it’s about what we do, not about what they do,” Crane said.The Eagle defense got the red-hot Crane the ball right back when Paul Anderson picked off a Mike Greco pass and returned it to the BC 24. Crane then continued to sling the ball around, completing two passes to Brandon Robinson, who caught seven balls for 109 yards on the day, and others to Jarvis and tight end Ryan Purvis.It looked like the Eagles were going to score again, but Crane overthrew a receiver and UCF’s Johnell Neal picked him off at the 15. But the BC defense forced a three-and-out, giving Crane and company another chance.This time, Logan’s crew went for the jugular as Crane hit Ifeayni Momah for a 46-yard gain to the Knights’ 13. Four plays later, Crane faked an inside give to James McCluskey and kept on the option for a three-yard score and a 17-7 lead.”This is only the fourth game that Chris has started, and that’s lost on some people,” Jagodzinski said. “I told Chris before the game to just go out and play like he was in his backyard and throw it around and have fun with it.”Crane nearly cost BC late in the third when he and Robinson miscommunicated on a route from the Eagle one, resulting in a Lawrence Young interception. But the Knights missed a 23-yard field goal early in the fourth quarter.”I should have thrown that in the stands,” Crane said about the miscue.Redemption for Crane and Robinson came moments later when they teamed to deliver the knockout blow. Crane’s 27-yard scramble on third-and-11 from the Eagle 31 set the table for Robinson, who caught an out on third-and-16 at the UCF 48 and turned it into a game-clinching touchdown.”The pass to Brandon was huge,” Crane said. “We needed a big pass play where somebody was going to do something above average.”Cra
