I can’t see this being a factor for us. We have no working systems in the forward half. The only way to improve without working systems is to get better players, which we seem to have achieved. Hopefully we can implement working systems to go with the better players.There is a theory that in the NFL that getting players from other clubs has an initial negative effect. As good as the player is they need to learn the systems of the team and the team needs to accept them. When breaking down teams in statistics, the player might be a big plus, but has a negative associated to joining the new team. The more you bring in the bigger this negative value can be (Port is a good example of that last year).
Player from the draft don't often play much in their first year so their negative is smaller.
So it is possible we might go backwards next year. Although I doubt it, because I suspect the players we drafted fill holes in our team, covering the biggest negative areas for our team.
Also rule changes are going to impact all teams systems so even mature, well drilled teams will have some bedding in to do.
