I'd say close to 50% of owners qualify as emotional owners. You're doing yourself a disservice if you let that be a nonstarter for you. Emotional owners can be least willing to trade a player or most willing to get someone off their roster. You just have to catch them at the right moment."I feel" is a non starter for me. Emotional fantasy owners are rarely productive trade partners.
@Hot Sauce Guy .. not trying to single you out here, there are a handful of posters going this route here. Not uncommon, I just can't relate.
In the thread that started this, I got accused of being an emotional owner because I counter garbage offers with my own garbage offer. I explained in that thread that it's not emotional, it's rational. If an owner isn't willing to spend time to put together a semi-plausible offer, then I'm most likely wasting my time if I spend time crafting a legitimate counter offer. The garbage counter isn't me slamming the door shut, it's just me reciprocating. I'm saying I see what you did there and I can do that, too. The fact I'm countering says the door is open, but I'm not investing time until they invest the time. After all, they want the player from me. Not the other way around. The onus is on them.

As for strategy, I like this time of year. I start looking at teams that are out of contention and then looking for 29/30 year old players. If their situations are stable, you're probably getting more years out of them than most people think. People who bought Fitz or Steve Smith at 30 probably don't regret it! Those are exceptions, but Boldin, Andre Johnson, TO, Reggie Wayne were all probably nice buys around the age of 30. It's risky, but low risk. You could very well end up with a Decker, Hogan, or... Dez.
If I'm making a decent player-for-player trade, I also like to ask for an impending FA (like a Kevin White or Moncrief) as a throw in if I have the roster space to spare because you don't have to hold for long - half a season. Robert Woods is a good example. You could probably have gotten him for almost nothing mid-2016 before his free agency. If Albert Wilson hadn't gotten injured, he'd be a good example, too. Chances are you'll end up with a Sanu or Brian Quick, but it never hurts to ask just in case...
