Re: Fourth Round...
there are some ridiculously good players still available in the 6th. one of the best things Texans did was stand pat in the first & get a premium OLB talent. Then trade back for more picks. I never thought Mercilus would last until #26, some very poor choices (good for Texans) before Rick Smith was on the clock. Whitney had a top 20 grade.
2012 Draft was Mercilus
