Let me first state that I think those defending him for being an undrafted free agent are fools. He was only undrafted due to his off the field issues.
However, last year, Landry led the league in drops, followed by Ridley, a first round pick. Julio Jones was tied for third. Edelman was tied for seventh.
The drops are concerning, but he's a rookie. His mind is moving too quickly. If they're this prominent next year, then yeah, it's an issue.
Those balls need to be caught, period.
