Since his arrival in the summer as the club's full-time defensive coach, there has been a sea change in Sale's rearguard with a club previously notable for the leakiest defence in the top-flight now among the meanest.
Such is the esteem with which Forshaw's work is held, director of rugby Steve Diamond last week revealed the ex-Bradford rugby league star had agreed a new two-year deal.
But as much as he is striving to shore up Sale's own Iron Curtain, Forshaw is also keen for the back-line to cut loose and start adding to the try tally.
Only Newcastle and Worcester have scored less points in their eight league games and Forshaw wants that to change.
"Defence is a massive area of the game these days," said Forshaw. "We're coaching the detail and we've got the detail in our system and our technical ability. But I'm with Brush (head coach Bryan Redpath) in that I want to see us attack more.
"Its not all about defence - I want to see us score tries. I've always said that we have got a talented back-line but the last few games we've probably done too much in the way of defending.
"Defence takes a lot out of you physically. We just need to start well and ensure we are not doing as much defending as we have these last few games.
"At Quins in the league and at home to Exeter when we went down to 13 men, we were under the pump in those first 40 minutes in both matches.
"We showed great desire but I want to see winning games and scoring lots of tries. I'm not just a defensive coach - at essence I'm a rugby coach and I really want to see us take the game to the opposition."
Rather than take the credit for turning around Sale's defence, Forshaw, who joined from Irish province Connacht, says the credit belongs to the players.
But he also fired the Sharks a warning that their hard work has only just begun and that any slackening in attitude or desire would be punished on the field.
"Defence is a massive area these days," he said. "It's not about being down to 13 men which we were against Exeter.
"I don't want to be in that scenario very often and we've talked about conceding silly penalties round the breakdown which is not acceptable.
"The great thing is we've got some very smart players here like Dan Braid, Dave Seymour, Johnny Leota and Sam Tuitupou to name but just a few.
"They have been a really good help to me and they are all great pros who helped drive what we wanted to do in pre season.
"But like I have said to the players, we can't take our foot off the accelerator. If you think you are the real deal you will get smacked and defence is an area we have got to keep working on and keep improving if we are to achieve our aims and have a real solid season.
"We're in the top five or six I think in terms of defensive stats now - the key is to ensure we are still there at the end of the season, that's what its all about."
