Most - - not all to be sure but most - - defensive backs are players who cannot catch the ball well. If they were reliable catchers, they would be WRs. DBs have comparable speed to WRs; they are agile like WRs. Other than the fact that WRs tend to be a bit taller on average than DBs, the most significant difference between the players who man those positions is the ability to catch a football reliably.

Carlos Rogers is an extreme example of this point - - but it is true for well more than half the DBs in the NFL.
