In the 2008 NFL draft, eight left tackles were selected in the first round. That’s some big money for some very big men. The right-handed quarterbacks whose blindside they would eventually protect would argue that it was money well spent.
In the picture above, #76 (dark jersey) is the left offensive tackle who is protecting the quarterback’s blindside (#8) – the side he cannot see – from a defensive player’s “pass rush” from the outside or off the “edge”.
