If I'm not mistaken pulling down can happen whenever. I remember last season looking at a DI drop down who was considering a conference member of mine after like the first cycle. With the guy I ended up pulling down that season, he dropped down maybe 2 cycles before signing started and I was the lead and only considering when that happened. I don't know if it would be possible to steal someone from a user coach who pulled a guy down, I would think the other guy would have a huge lead by being the team to initially pull him down, but I guess if the prestige gap is large enough it could happen.
