NFL Wide Receiver Expected Catch Totals

| by

One of the neat features on the individual stat pages are some receiver stats you don't typically see. There's targets, target percentage, yards per target, catch rate, and deep percentage. Occasionally you'll find target stats on conventional stat sites, but I think target percentage is more interesting--the percentage of team targets each receiver gets.

The other day I was sorting the WR stats page by Catch Rate (CR), which is simply receptions per target. I wanted to see which guys had the better hands. To no surprise, catch rate is closely related to how often a receiver is thrown deep balls. Deep% is the proportion of targets thrown in the air deeper than 15 yds past the line of scrimmage. The relationship between CR and Deep% for receivers with at least 40 targets in 2009 is plotted below. The relationship in 2010 shows virtually the same pattern, but is slightly more scattered because of the smaller sample.

 

I thought it might be interesting to calculate the expected CR of each receiver based on his Deep%, then calculate the difference between his expected and actual CR. Graphically, the difference between expected and actual CR is the vertical distance between each receiver's data point and the trend line. This might give us an idea of who the receivers are who can reliably pull in the most passes. Obviously, there are more factors in play than just the receiver's performance, including the QB, offensive line, other team receivers, game situations and opponents, among other factors. But the correlation is considerable at 0.47, and at the very least, it's one piece of the puzzle.

For the 2010 season (through week 6), here are the leaders in Catch Rate Above Expected. There seems to be some sort of connection between having a hyphen in your surname and dropping passes.
