Arsene Wenger proposes a change to the offside rule that would mean attackers are onside if any part of their body is in line with the last outfield defender.
I think my point is that, also with the current rules, you have to make the decision of whether to fall back or commit to an offside trap before the ball is passed. I don’t think this change would affect that choice significantly, you’re already likely to concede a goal if an offside trap fails.
Of course, most modern defence is built around area denial rather than directly following runs, but once you commit to following a run you don’t wait idly for the pass and pray for an offside. I think the game would be played very similarly, but with more hairline-decisions going in the attackers favour.
