Yes, Moss can get open better than Rice, but.....
Rice after year 2 made adjustment's to GO FOR THE BALL. Moss, no. He runs his pattern, if the ball doesn't float into his arms, he runs his pattern still...
TO. Same as nowadaze Moss. He could make spectacular catches, but more often than not shortarms the ball that lands on BOTH his hands without breaking stride, his elbows bent 90 degrees. He needed warmup catches before the real thing.
Either way, getting open to entice the QB to throw your way is nothing like making the effort on every ball to CATCH IT!
Effort is not related to talent, or god given physical ability.
