It's a little more intense than changing a tire, yet not as intensive as a complete engine overhaul.
The BMW that was the Winnipeg Blue Bombers coming into the season looks more like a used Ford Escort these days, complete with a loose steering wheel, a broken stereo, some leaking fluids and a few rust spots.
Sporting a 1-5 record at the one-third mark of the season, head coach Doug Berry said there would be changes heading into Friday's home game against the Montreal Alouettes. What those changes are remains a secret.
One thing is for sure though. Ryan Dinwiddie will get his third consecutive start at quarterback.
"We go back to two weeks ago to the outstanding game he had (but) this past game he was so-so,' said Berry. "it certainly wasn't a debacle on his behalf, nor did he totally make things happen by himself, which not many people are going to be able to do. So I'm willing to let him go out and get another shot and try to get to where we were two weeks ago."
Likewise, don't expect to see any changes in the backfield. Charles Roberts will get the call against the Alouettes, despite only rumbling for 66 yards in last Friday's 19-11 loss to the Toronto Argonauts.
"I evaluated all that we've done with Roberts all year and particularly in this last game, this was probably as good as he's been able to perform all year long in terms of average and big plays," said Berry.
"He had two runs in this game that were bigger than any two he's had already this year, so it's good to see that. I know that Charles is very motivated to continue to improve and I'm willing to watch that develop."
One area that could see changes is at receiver but not by choice.
Milt Stegall, who played his first game of the season on Friday, did not practise yesterday.
"I think Milt needed a day, we'll see where he's at and whether or not he's ready to go," said Berry.
Receiver Terrence Edwards also missed practice yesterday. Edwards, Berry said "re-aggravated his ribs and it's a day-to-day thing."
The receivers, most notably Romby Bryant who leads the league in receiving yards with 580, have been one of the lone bright spots for the Bombers this season and if too many of them start missing games, Winnipeg's offence could become completely abysmal.
Berry still remains optimistic about the rest of the season.
"All we're going to do is say that we've got a 12-game schedule in front of us and that with this next game, if we win it we're 1-0, if we lose it we're 0-1, but we've got a 12 game schedule," he said. "We can't and won't let the first six games effect what we're going to be doing in the future.
"I believe (the players) are as optimistic as I am, so I think we're going to believe that we're where we want to be and need to be and we're going in that right direction. It's all about attitude and that's what I'm trying to correct around here."
