Guys, just stop playing on HOF. HOF has been f^cked for years, there's so much cheese it's absolutely unbearable. All this "scripted" talk is clogging up the thread, it's just cheese and if you play on HOF you're asking for it.
I'm wondering this too. When I first encountered this question I was ecstatic, 'cause I figured as long as you perform well enough in the showcase to be drafted at your favourite team's spot or above, you'll go to that team. No dice. Most likely it affects your chosen team's interest in you, but trades are still very hit and miss so I don't think it helps much. And given how bugged out this game is, it might even be glitched and actually prevents you from going to that team.
