"I'm very, very disappointed considering there's 41 players there and we haven't got one forward out of the 22 or whatever it is forwards", said the Scot.
Scotland finished fourth, above Wales, in this season's Six Nations and Telfer thought Hamish Watson and John Barclay were unlucky to miss out.
"When you look at the half-backs Wales, Ireland and England have and in terms of the schedule you've got running into our prep, I think when you play together you've got a natural combination".
The Lions will play 10 games in New Zealand, including three Tests against the All Blacks.
"I certainly wasn't that mature going into the last tour but now I fully believe I am and as I say I was a better player coming off the back of that".
"We couldn't leave Jamie out".
"The prognosis with him is a lot more positive than was first diagnosed in terms of it's an unusual injury with a capsule thing, or something, but the prognosis and the recovery is hopefully a lot better than what was potentially first suspected".

"Those are the sort of players, with no disrespect, who might struggle to make the first test team but they will be giving everything they can on and off the field". And Iain Henderson has done an exceptional job for Ireland. I guess we need to be prepared for what we normally get and prepare for something different as well. "They're different players and if we'd left out Courtney we'd be asked the same questions".
