... and blocking

The announcers were falling over themselves praising Tebow for that first down run in the third quarter, and it was a good run. But he almost surely would have been tackled short of the line if he hadn't gotten a very effective block from the receiver, who spun around and blocked a safety (it appeared) across the 20 while Tebow was on his way to the same spot. It's so easy and natural to give all the glory (and blame) to the quarterback, and skill position players generally, but you would expect the broadcast announcers to bring a higher level of sophistication.
