Rigg’s Exeter debut came as a replacement away at Newcastle in March, with his first start coming a week later at Sale where he lined up against the likes of Manu Tuilagi, Rob du Preez and George Ford.
His first start this season came against Harlequins, where he also scored his first top-flight try, before touching down three times in Exeter’s subsequent two Premiership Cup matches.
“I think his ball carrying is improving all the time and you’re seeing that at this level where in those Prem Cup games he looks a very dangerous ball carrier,” Exeter director of rugby Rob Baxter told BBC Sport.
“What we’ve got to try and do is almost kind of keep that confidence to get on the ball and carry hard and find that space and attack the space.
“We’ve adapted our defensive system a bit, everyone has seen that, and I think that will suit him a little bit more and give him a little bit more time to assess what his defensive responsibilities are.
“But certainly in the last few weeks he’s really starting to take off.”
