I want them to go for impact players all through the draft. Where people may disagree with me is that I feel like a really good gritty 4th liner can be an impact player on a team... especially if he is signed to a good contract and developed in house.
As for the percentages, I think the biggest drop offs are way at the top of the draft... after that the drop-offs get smaller and smaller... really outside the top 10 you are statistically probably going to get an NHL regular.... not more. By the time you hit pick 20 you are looking at fringe NHLers on average... and that continues until about pick 100 more or less.
Here is a fun article about that:

As fans we look by round and we expect Mike McCarron to be a great player because he is a "1st RD pick" ... but actually he is doing ok relative to where he was picked and he actually is in the same tier as DLR & Fucale & Lekhonen... but the latter 3 seem to get a free pass because they were picked a few spots later.
All I know is we BETTER DAMN WELL hit with the 3rd overall. It's a legitimate chance to get a building block type of player...and we need that sorely. Let Timmins do his thing with the 4 seconds. The past few drafts have been much better so I'm hoping that trend will continue and we will snag a goody with one of those...
