A recruiter comes out to watch you play.
Let's say your team has a total of 40 offensive plays in that game. And let's say the QB throws the ball your way four times. Finally, let's say you caught only two of those four passes. Is that enough for the recruiter to go on and make an educated evaluation? Yes, you bet. Were you directly involved in 10% of the plays that night? No. You were directly involved in 100% of the offensive plays that night.
The ball got thrown your way four times, you caught two. What did you do on the other 36 offensive plays? Recruiters will evaluate your pre-snap reads to post-snap adjustments.
What did you do (or not do) when the ball was not in your hands the other 90% of the game? The little things count. Stance and start, releases against man-press coverage, stacking the DB and staying on your route, stemming, footwork, handwork, top of the route breaks, discipline, stalk blocking, cross field blocks, hustle between plays, leadership. It all counts.
What you do when the ball is not in your hands, which will be a lot as a wide receiver in any offense, counts more than what you do with the ball.
