Patriots tight end Rob Gronkowski spent last offseason answering questions about whether he’d be ready to go for the season opener, so he’s familiar with the line of questioning he’ll be facing for the rest of this offseason. Gronkowski tore his ACL on December 8, ending a season that started late after the tight end recovered from forearm and back surgeries and starting the clock on several more months of uncertainty about his availability. Based on his response to a question about being ready for the season opener, that clock will continue to tick for some time.
