The Vikings signed John Carlson this offseason to pair with second-year tight end Kyle Rudolph, drawing comparisons to New England's excellent combination of Rob Gronkowski and Aaron Hernandez. In 62 NFL games, the Minnesota tight end tandem has 163 receptions, 1,768 yards and 16 touchdowns. "To compare us to those two tight ends is not something I'm going to do right now," Carlson said. "We've got a lot of work to do; we have a long ways to go. It's been done. It's being done out there. We have to work to improve to get toward that point."
