Here's 2016s numbers.
Inside the 20
Robinson, 9 catches on 19 targets
Landry, 7 catches on 9 targets
Narrow it down to inside the 10
Robinson, 5 catches, 11 targets
Landry, 4 catches, 4 targets
Furthermore, this season, Landry developed into one of THE best redzone receiver in football.
Inside the 20
NFL leading 18 catches on 23 targets. Oh and 9 TDs. Only Jimmy Graham had more.
Inside the 10 is even better
NFL leading 11 catches on 14 targets with an NFL leading 9 TDs.
So this season Landry is the unquestioned best receiver in football in the redzone.
The explosion you hear is the Robinson being a better redzone target argument.
