OWLS new boy Joe Mattock is staking an unexpected claim for a place at right-back.
Although a recognised left-back, he figured on the opposite flank in the last two friendlies, against Reading and Doncaster.
“We’re just looking at different things,” said manager Dave Jones, who has been starting with Reda Johnson at left-back.
New right-back signing Kieran Lee was an unused sub in last Saturday’s 0-0 draw at Doncaster, and last season’s first choice in this spot, Lewis Buxton, has yet to play after a shoulder operation.
Jones also pointed out that he replaced Johnson with Mark Beevers at left-back for the second half at the Keepmoat Stadium.
It was the position that Beevers filled at the back end of last season when Johnson was injured.
Jones added: “The more people you’ve got who can play in different positions, the better.
“It means that if someone goes out or is away from their normal position, someone else can fill in there and be comfortable there, as well as being comfortable in their own position.
“We’re just mixing things around and looking at different pictures.”
Jones is satisfied with the progress his squad are making on the fitness front. “They’re all good athletes. They’ll be playing against a lot of very good players next season. We have to be ready for it,” he said.
Jermaine Johnson is back in training and has suffered no ill effects after the friendly at Doncaster where he went off early, as a precautionary measure, with a tight hamstring.
Buxton, still building up his fitness after his early-summer surgery, is expected to step up his training in the next few days.
West Brom’s ex-Owls star Chris Brunt may miss the friendly at Hillsborough on Saturday.
He has been out with a calf injury but Albion expect him to be fit for the start of the season.
