All three will hope to push their claims for a place in the 22 for the second Test on Saturday - after the Lions lost the opener in Durban - during Tuesday's game against the Emerging Springboks, with Hines probably the most likely to receive a call-up.
The situation is in stark contrast to the victorious 1997 tour when Tom Smith was one of the heroes at prop, Alan Tait scored a try on the wing and Gregor Townsend was in such fine form at stand-off he forced Ian McGeechan to select crucial goalkicker Neil Jenkins at ful-back.
Rob Wainwright also played his way into the side for the third Test and Doddie Weir was a respected member of the party before having his tour cut short by injury.
Logan said: "The problem Scotland have is we have just two professional teams, Glasgow and Edinburgh. That means there is only a limited number of players to select from.
"Ireland, for example, have four provinces and now have half the Lions team. So I suppose in that respect it's not that surprising we're struggling for Lions players."
