He’s 6-foot-2 227 pounds. Big enough that he’s hard to miss. He was a famous quarterback when he was 15 years old. By 21 he was a star in a city known for them. And yet he’s been almost invisible over the last few months. It has not been a banner training camp for Matt Barkley so far. The headlines and the local curiosity have centered on Michael Vick and Nick Foles. The snaps with the first- and second-teams have gone their way too. The spotlight once Barkley’s to bask in by his lonesome is focused on the other two -- and so he has spent most of his time on the sideline in their shadows. During practice against the Patriots at the NovaCare Complex this week Barkley barley saw the field. He took just nine snaps on Tuesday and only 10 on Wednesday. He did more standing and watching than throwing and improving. The quarterback competition? It involves two guys. Three is evidently a crowd. Barkley knows it. Earlier in the week he said the situation “can be tough” at times. When he was pressed about the rookie’s decreased playing time in practice Chip Kelly got chippy said “camp’s not over” and “you’ll see a lot of him Friday night.” Barkley played quite a bit in Friday night’s 31-22 loss to the Patriots at Lincoln Financial Field (see Instant Replay). That much is indisputable. How well he played is less concrete. Barkley threw 22 passes which was double the attempts by Vick and Foles combined (see story). Barkley completed 11 of his throws for 103 yards. That’s 50 percent and 4.7 yards per completion average.
