To be honest nothing about this selection changes my opinion about the Lions chances. There's very little drop off in most positions no matter who Farrell picks (especially the 7 jersey), I don't think pretty marginal calls will be what decides the series, they should win if they are in any way cohesive. If they play like the did against the Argies, the only real challenge they have had on this tour, they could get beat up for their lunch money, but they really really shouldn't.
My only concern from a Lions POV is the balance of the bench. I wouldn't want Smith playing significant minutes at 15.
