Drafting is not an exact science

When it comes to the NFL draft, there are a lot more theories than hard-and-fast rules. But some theories, when widely implemented, turn into trends. And after a while, those trends can start to look like rules.

In reality, though, most so-called rules of drafting NFL players are more like myths. So we decided to put together our own little version of "MythBusters" and try to sort out fact from fiction. We've focused on 10 common theories you're likely to hear a lot the next few weeks -- essentially, the do's and don'ts of drafting -- and dug into the history books to see which hold up and which get busted.

1. Offensive tackle is the safest position on which to use a high pick
This theory built steam in the late 1990s during a remarkable run of tackles selected in the top 20 overall, including Jonathan Ogden (Ravens) and Willie Anderson (Bengals) in 1996; Orlando Pace (Rams), Walter Jones (Seahawks) and Tarik Glenn (Colts) in 1997; Kyle Turley (Saints) and Tra Thomas (Eagles) in 1998; and John Tait (Chiefs) and Luke Petitgout (Giants) in 1999.
