Interesting link, something to read on a slow day.
Most teams use cut blocks, the problem for the Pats this Sunday is Denver's line is infamous for the chop block, where one OL is drive blocking on the DL, and a second OL dives in to the DL's legs. Atlanta, current home of the filthy Alex Gibbs who teaches this technique and started it at Denver, was doing it on almost every play in the pre-season and was completely ignored by the officials.
The best place to watch for a good cut block by either the Denver line or the Patriots, is on the backside of a stretch play. You'll often see the OT cutting the DT and ignoring the DE, this is intended to free up the OG to get out on a LB. Another place you see them are quick throws into the flat, Gorin was quite good at cutting the legs out from under the DE as he pass rushed - it isn't as important to get him on the ground as it is to force his hands down so Tommy has a clear throwing lane.
