Hartselle Tigers (15-0) 5-A State Champ
He's a fairly talented receiver, but he's just not worth it. An elite receiver makes that catch on the deep ball where it went right through his hands. He's sloppy most of the time.
A professional receiver shouldn't be trying to catch any ball with his hands that far apart to begin with. That's a lack of fundamentals.
The closer he gets to the endzone, the worse his route running gets. He runs terrible routes in the redzone.
He does little things that tip off the defense as you mentioned (leaving the huddle early when he's not getting the ball, etc.)
Drops a ton of passes because his technique gets so sloppy.
The fanboys in their #19 jerseys will keep defending this bum with a bunch of "ifs"... but he's not nearly what they think he is.
