Pound for pound, one of the best-ever signings made by Rob Baxter here at the Chiefs.
Since arriving at Sandy Park from Ulster Rugby in the summer of 2012, Whitten has been a stand-out performer for the Devonians, helping them to two Premiership titles, as well as a first-ever Heineken Champions Cup.
Recruited to the Ulster Academy in 2007, the Lisburn-born back spent four years with the Irish province, representing them not only in the Magners and Pro 12 Leagues, but also in European competition as well.
It was during the 2008/09 season that he made his Ulster debut in a Heineken Cup fixture against Stade Francais and he went on to establish himself in the side for the rest of the season. This culminated in a call-up to the Ireland squad for the summer tour of USA and Canada, where he won two senior caps.
Whitten continued to figure in the Ulster squad right up until his depature in 2012, where he cited he needed a fresh challenge and to test himself in a new environment.
The Chiefs clearly liked what that saw of Whitten and it was not long before he was making his mark for his new club. Equally adept playing in the centre or on the wing, the Northern Irishman made his debut for the Devon club in a Premiership fixture away to Sale Sharks in September of that year.
His hard-running style, his try-scoring ability and his excellent defensive work have seen him become a regular fixture within the Chiefs set-up over the years and against Saracens in the 2017 Premiership semi-final he notched up his 100th league game for the club.
Now with over 200 games to his name, he remains one of the cornerstones of an Exeter side which continues to challenge for honours each season.
