Reed had a solid rookie season for the Redskins as he became one of Griffin's favourite targets throughout the campaign, before injuries halted his progress late in the year.
The quarterback feels that the 24-year-old will go from strength to strength in his second year in the NFL.
"I think he's one of the most talented tight ends in the league," Griffin told Fox Sports. "He'll have an opportunity to show that.
"He's a guy that runs some of the best routes I've ever seen. Our offensive coordinator, Sean McVay, has said that you can't cover the guy.
"If [Reed] knows what he's doing, where he's going and he knows how he's trying to get there, you can't cover him. That's a good asset to have."
Reed recorded 45 receptions for 499 yards and three touchdowns in the 2013 season.
