@fiorite- The key to the west coast offense, whether using a wing T or an empty backfield, is an accurate, athletic quarterback and receivers with good hands who are not afraid to take a hit. Quarterbacks in the west coast need to be able to look off the defenders and put balls into tight quarters. Running backs need to be able to pick up yards, be active in pass play, and have good pass protection abilities. Receivers are usually smaller, route running specialists that have good after the catch ability. An example of a great quarterback that could run a west coast offense would be Brett Favre.
Teams that still use the West Coast offense are the Eagles, Seahawks, Cardinals, and the Broncos, although their version is different from the rest. Other teams like the Raiders, Patriots, Texans, Ravens, and Chiefs use the West Coast offense often. Many of these teams are still very good, or have good offenses, proving that the west coast offense can be effective.
