1) depending on the size of the league, waivers is the easiest and quickest way to help rebuild your team. It gives you guys to use for trading and guys to use for keeping later. Trading is possible, but frankly it's easy to dominate a trade with a last place guy. They have to hit on a lot of players long term to get out of the hole. The draft is so few players that it could take 5 or 6 years of sucking to field a competent team from rookie drafts.2) like I said before, in dynasty, blind bid is a double edged sword. If you are a cellar dweller you rely on waivers for trade bait and to improve your team. While due diligence can tell you who to take and who not to, what it can't do is tell you how much other teams are going to bid on what players and which ones will be good long term with any kind of certainty. Let's say last year you were in a full rebuild. Victor Cruz is on your radar after week 1 (we will pretend he was not on a team). How much do you bid on him? Let's say he emerged in week 2, how much do you bid on him and McCluster? (he was going for the Charles roll). Which was more likely to succeed? An UDFA as a teams WR3 or a guy sharing carries with Thonas Jones?The point is that it's impossible to tell how much to bid on guys, and teams at the top can afford to overspend because guys like Cruz last year were luxury pickups if they had a proper team construction. In order to get Cruz you had to blue a large portion of your FAAB, which also meant you were less likely to get OTHER players. And if you spent a lot and Cruz didn't do much else it was a wasted pickup
