Well the project 2 player would be listed as so in their roster thread. If say I were to have created one and he was in the VHL in 2 seasons. Noel hits season 4 and I wanna give up on him. I then apply the carryover to my P2 player and he becomes the go to player. Noel retires properly and P2 player is now just P1 player. I can then go and make another P2 if I want to. I was hinting at the point of some people kinda want to avoid the VHLM with their player. This would give them an outlet to do so.
P2 hits the VHLM and they kinda can forget about them almost except for the updating. They still have their main player to focus on and that is cool. Once they are ready to retire their P2 will be getting ready to be drafted and after they do get drafted they almost get to skip the VHLM kinda. With how it is normally, you retire and recreate and get stuck in the VHLM for 1-1.5 seasons. This would eliminate the hard focus on those 1-1.5 years and allow for those to "technically" skip the VHLM and they could go about their career with the carryover and enjoy that P2. It's a win win because the VHLM still gets a player for roughly 2-3 seasons and then the other person don't have to focus so much on their P2 outside of updating them. They would still start at the 30 with no carryover obviously, but it could be applied later to help bypass the "VHLM Phase" that some people kinda want to skip.
