This drill is very misleading because it gives so much space to the defender that it causes 'wins' for defenders that are simply unrealistic in games, and exposes certain OL by exploiting them as if they were in a worse situation than a LT is in. It's like an LT, except instead of having unlimited space to one side (the LT's left), this drill provides unlimited space to both sides and the 'QB' never moves so it is equi-distant in both directions. This leads to the OL having to 'reach' a lot and simply looking like they lack technique, when that simply isn't the case.
These particular OL are all interior linemen specifically because they aren't good enough at defending space to merit it in the NFL, and most don't even merit it in college. Some have slow feet, others poor technique, most stiff in the bend, and a lot of them have short arms compared to their T bretheren. You see many OL standing higher and more on the balls of their feet with their weight over their feet to allow them a better chance to counter laterally quick DL; which inevitably leads to them getting bull-rushed, being thrown off balance, and looking weak. In a game they'd have help on one side and very little space to cover on the other, so they can get nice and low and defend those bull rushes well. You will see these DL run roughshod over the OL in this particular drill, but it is even less indicative of the OL's ability as interior linemen than watching the pre-season practices without pads.
So, when you watch this, realize it's kinda like testing swimmers in a 40 meter dash on a track field ... it's not really testing what they'll be doing in the NFL.
