Sam Bradford has completed less than 50 percent of his passes through four games in part because his teammates have suffered from a league-high 12 dropped passes.
I've put together an updated chart showing every NFC West drop this season. ESPN Stats & Information defines drops as incomplete passes where the offending player should have caught the pass with ordinary effort, and only when the receiver is 100 percent at fault. Passes thrown just outside the receiver's reach or those falling incomplete when pass interference should have been called do not meet the standard.
The chart also shows how many times each player has been targeted. Targets show how many times a player is targeted, whether or not a catch should have been made. Note that the San Francisco 49ers' Vernon Davis has 19 receptions in 23 targets, a very high percentage.
The Rams' league-high total is two more than Cleveland. The 49ers have seven, which is tied for seventh-most. The Arizona Cardinals have three, tied for 26th-most. The Seattle Seahawks have two, none by wide receivers. Only the New England Patriots, with one, have fewer.
