This is my 2nd season back in the game and I'm at D2 in the first recruiting session now. I'm recruiting a D1 player and have offered a scholarship and everything else you can give him but a D1 school has shown interest now. Session 1 ends in 3 days (2/13) and of course I can't sign him until session 2. Am I going to be able to hold the D1 school off or should I man the lifeboats and look for backup? Thanks.

Is it a human D1 or a sim D1?

If it's a Sim D1, assuming you are at Moderate and the Sim didn't get above Very Low, it will not make a further run at the player.
If it is a human D1, you might want to pick up the Yellow Pages and look for Plan B -- a human D1 moving in on a recruit that has been offered a scholarship and is at Moderate has probably chosen to engage for one and only one reason -- to get the recruit.

There's also the question of when the recruit signs. Is it an Early or End of Period 1 recruit that will sign on the first cycle or before if the D1 gets, or is it a Late/Whenever recruit that might not sign until well into the second session, giving the D1 even more time to catch up. Also good to calculate how much of a head start you had on the D1 -- how many AP do you have invested? Did you make any promises that will compound effort? Or have you done just AP and the scholarship so far? With 3 days until signings end, I'm guessing you didn't have that big a head start on the recruit before the D1 came in.

There are a lot of variables, but if a human D1 wants the recruit, I would say it'd be pretty hard for a D2 to hold off for at least 3 days. And even if you do, you're probably going to be in a random number generator situation and playing percentages, not assuring yourself of actually getting the kid.

Excellent questions!
Recruit wants to sign by end of recruiting session 1. Human D1 owner (they're the worst kind).
I can continue to give a lot of AP if I don't switch to another player but my max is 80 AP's /turn and I'm not sure what D1 can do? They say everything they do is "more valuable" so that's an unknown for me, too.
I've done scholly, campus visit, home visit, playing time, everything but a promised start (which I don't want to do).

The D1 team blew by me at 11am today. It didn't take long. I had decided to move on by then, which is fortunate as I have D1 sims after some other recruits.
