you're responding to a guy who believes good offensive lines regularly give rbs 4-5 yards before being touched.
I don't think so highly of him, but I can recognize on tape when a guy can seal a running lane. There are more good blocking tight ends, sorry I didn't feel like naming them all I just tossed a couple names out there. But if you really think your average 250 pound tight end, who in todays league is required to be athletic enough to also catch passes, can blast a defensive end or outside linebacker off the ball at the point of attack you're really blinded by the realities of modern day football. You're right though, if you run misdirection plays you're certainly running the same play at all times.
