I actually did the math
HF Staff got .0666% correct in the first round (2/30)
TSN got .0333% correct in the first round (1/30)
Redline got .1333% correct in the first round (4/30)
ESPN got .1000% correct in the first round (3/30)
Here's the ISS ranking of the first round with mock draft prediction in parentheses. After the player's name, I list where the player was taken. You folks be the judge, but please keep in mind, our ranking is our opinion of a player, not a prediction of how high he'll be drafted. Our mock draft does that.

Based on the criteria that was used by the above poster, you have to have it exactly right to make it count. Our rankings matched three of the picks (the top three); in our mock draft (which we don't spend nearly as much time on as our rankings) we predicted three of the first round exactly right.
Really, I think to get a more accurate assessment of a draft prediction, you should not measure how many picks are exactly right. As Jaded Fan suggested, you should measure how far off you are from the actual selection, then divide the sum of those misses by 30 (if you're evaluating a first-round prediction). I don't say this because we would do better -- I don't know because I didn't take the time to see how we or the the various services did -- I just think it would be a better way to assess the prediction.
But, as Bob MacKenzie said, if you want to evaluate our rankings, do it 10 years from now after these players have played in the NHL and compared what kind of careers they have. We're not really in the business of predicting where players will go, we're in the business of forming an opinion of where a player should go and selling that opinion. Some teams buy it, some teams don't and the teams that do, certainly don't treat us as gospel. They all have their own scouts and we're a second opinion.
