I found an article that articulates what I was trying to convey....

Picks 51-100: *BEST VALUE*
The running back position has been devalued over the years, as very few bell-cow backs have earned a place in the top 20 overall because of attrition at the position. Look for Anthony Dixon, Jonathan Dwyer, Toby Gerhart, Montario Hardesty and Ben Tate to be selected in the third to early fourth rounds

Picks 21-50: *BEST VALUE*
The interior offensive line class is fairly thin, so any teams looking for a difference-maker inside must break into the bottom half of the first round or top half of the second round -- Jon Asamoah, Mike Iupati and Maurkice Pouncey could all be chosen in the first round.

Picks 51-100: *BEST VALUE*
Teams will reach for big bodies who can anchor the middle of their defense, especially those looking for a nose tackle in a 3-4 defense. Cam Thomas and Torell Troup will go higher than some expect because of the need for stout run-stuffers, as may Arthur Jones and Jeff Owens. Tyson Alualu, Geno Atkins and Lamarr Houston could also get calls in the second or third rounds to be defensive ends in three-man fronts.

Picks 101-150: *BEST VALUE*
There are major questions about all of the ends listed in the top 100, save Derrick Morgan. Greg Hardy, George Johnson, Brandon Lang, Daniel Te'o-Nesheim all have enough upside that their value isn't significantly different from Carrington, Cunningham or Lane, meaning teams might be better off waiting to meet this need until Saturday.

Picks 21-50: *BEST VALUE*
Look for a run on corners starting somewhere around the 20th pick with Kareem Jackson, Devin McCourty and Kyle Wilson probable first-rounders likely to land with the three or four teams looking for help at the position. Chris Cook and Patrick Robinson won't be far behind the top tier. Depth at corner continues to be very good in the next two groups, as well, with Dominique Franks and others potentially sneaking into the mid-second round and strong value likely available in the early-to-mid fourth round.

Picks 51-100: Dominique Franks, Brandon Ghee, Jerome Murphy, Akwasi Owusu-Ansah, Amari Spievey
Picks 101-150: Javier Arenas, Perrish Cox, Walter McFadden, Kevin Thomas, Alterraun Verner

Picks 51-100: *BEST VALUE*
Though some consider the safety class as deep as it has ever been, the value of this year's class is in the same place it usually is: the late second and third rounds. Morgan Burnett could sneak into the top 50, but Chad Jones, Reshad Jones, Darrell Stuckey and Major Wright will all contend for starting jobs as rookies for several teams looking to upgrade their defensive backfield.
