Hugh said in today's Herald: "We don't have a lot of players running out of contract at the end of the season, so there were always going to be more signings at Edinburgh."
"I don't want to keep blaming our injury problems for our inconsistencies on the pitch. But training and preparation for vital games can be very difficult when you have only 20 members of your squad available.
"We lost to the Borders because they had experience we didn't possess. At half-back, they had two Lions in Chris Cusiter and Gregor Townsend while Samoan Test captain Semo Sititi was in their breakaway unit.
"We have an extremely talented crop of young players, but they lack maturity at this level - and the ability to know what to do and when."
Meanwhile, the operation to repair Rory Lamont's broken jaw went well. He's now recovering and hopes to be back in a Glasgow jersey in 4-5 weeks.
The Scotsman reports that Edinburgh scrum-half Rory Lawson turned down the opportunity to move to Glasgow in favour of a two-year contract with Gloucester.
