On the first play of his first NFL game on Thursday night Tampa Bay Buccaneers rookie quarterback Mike Glennon did exactly what he did not want to do. He panicked. But with the Baltimore Ravens pass rush closing in he also showed some poise quickly gathering himself at Tampa Bay’s 6-yard line and finding tight end Tom Crabtree downfield for what turned into a 61-yard completion. “My initial read wasn’t open and I started panicking’’ said Glennon a third-round draft pick from relieved starter Josh Freeman late in the in the first quarter. “I was actually going to take a safety there. But then all of a sudden Crabtree flashed on me. “I didn’t know if he was going to take it to the house or not but that was definitely a pretty unique way to kick off my career.’’ The play set up Derek Dimke’s 35-yard field goal for a 6-0 lead. Though the Bucs lost 44-16 to the reigning Super Bowl champions Glennon complete 11 of 23 passes for 169 yards no touchdowns and one interception. He also managed to make a good impression on head coach Greg Schiano. “It got a little dicey there (on that first play) but that’s one thing Mike does well — he keeps his cool and he was able to find Tom so I think he did a good job running the operation’’ Schiano said. Glennon is second on the Bucs depth chart behind Freeman and ahead of veteran Dan Orlovsky.
