So how do a team missing so many of their big names manage to put in their best performance of the season, as Glasgow did in their 22-19 win over Bath on Saturday?
This was, after all, supposedly a weakened Warriors side, with key players such as George Horne, Sione Tuipulotu and a host of others rested. And a dozen others were on the injury list, including Sam Johnson, Rory Darge and Zander Fagerson.
Yet they took the game to Bath in the opening minutes, and, although they had to defend to the death, they had the chances to wrap up the victory some time before Duncan Weir’s late penalty regained them a lead they would not relinquish.
