Teddy Bridgewater worked about 14.5 months to get to this point. Three months, he figures, were partially spent responding to the 800-plus messages he received after the devastating knee injury. “I made it my business to respond to every text message,” Bridgewater said Thursday, three days before he’ll suit up Sunday in Washington for the first time since August 2016. There’s no educated guess for how long it would take Bridgewater to respond to messages he’ll receive if he makes a successful return to an NFL field. As the Vikings backup quarterback Sunday, Bridgewater will be one play away from that reality — and from achieving his latest dream so long in the making. “Once I get out there between those lines, I have no regrets, no doubt,” Bridgewater said. “I’m just out there living my dream. There was a time where the dream may have ended or died, but the dream is still alive.” The Vikings are waiting until “everybody is comfortable” before starting Bridgewater, according to coach Mike Zimmer, who pointed out Bridgewater has not had the benefit of an offseason, training camp or even preseason game to establish his knowledge and rhythm in Pat Shurmur’s offense. But Bridgewater has “no concerns at all,” he said, despite working to still improve his mobility with a brace supporting his surgically-repaired left knee.
