I personally almost never look at the projections. There's just simply no way that Yahoo can accurately predict sleepers who blow up every year. Most of their projections are simply just taking what the player did the previous year and tweaking it a minor bit. Obviously, for players like LBJ, CP3, and Kevin Durant, you're not going to be too far off if your projections are based on last year's numbers since they will put up studly numbers year in and year out. But when it comes to mid-round guys, their projections don't really help much at all.
Case in point, when D.Wright went to the Warriors for the first year, Yahoo did nothing to predict that he was going to blow up and be top 35 by the end of the season. But then the following year, they projected him to be top 50 because of his stellar first year and he absolutely flopped after people reached for him in the 3rd round.
This is why you should never trust or base your strategy around Yahoo projections. They suck monkey balls
