Many draft experts were looking more at Damontre Moore DE from Texas A&M or Tank Carradine DE from Florida State as a replacement for Dumervil, and Werner who was already drafted.
There were also two highly rated ILB on the board in Alec Ogletree and Manti Te'o still on the board. Moreover, top RB Eddie Lacy from Alabama was also on the board, so Williams selection was questionable, and perplexing.
The Broncos may also be looking at going back to Dwight Freeney at DE after the draft.
It really remains to be seen if Williams is an impact player, and I will wait to see some results in preseason.
