Here's something interesting for people to ponder.
The only trade I regret this season is one I didn't do. Raines -> Gilbert after round 2. It was all set...I was even on the final confirmation screen when I pulled out and saved the trade. Would've netted me a lot of extra points (Gilbert vs my back EMG Suban), and gotten me a cheap as chips keeper.
Yes, you can be conservative, and generally when you're not sure then don't trade. However, sometimes you've got to trust your gut and back your judgement. I picked Gilbert as being a break-out player if he could secure a backline spot in the Saints side. It was clear after roudn 2 that he had secured the spot, but i didn't back my gut feeling, and I've regretted it.
