Back in Version 1.0, if you offered a booster gift to any recruit who had two "greedy" references in his scouting reports, they would usually accept, a little more than 50% of the time. You were seldom investigated, and not always penalized if you were checked out. It was a little extra fun to be had with willing recruits. I think I offered 17 or 18, because there weren't many such recruits, and I only got probation once. About par for those who taught me the tricks.
In V2, I think I tried it about 5 times, they seldom accepted (only once, I think), I got investigated twice and put on probation once.
But V1, that was the good old days. Back then, in addition to booster gifts being an occassional option, you knew what game plan you needed, what recruits you needed, you could build up war chests, and you could recruit players specifically to flip to another position. It was a different game back then. Oh, the fun we had. If V1 was still the engine, I would probably be coaching 10 teams.
