If you watch the film on Smith, his route running and especially his relentlessness are the best I’ve literally ever seen coming out of school. I didn’t see Rice coming out of Mississippi Valley, but Smith is a total professional with his craft coming out of school.
One thing you will notice on the film is when the ball isn’t even going his way. He’s cutting hard, over and over to try to get open no matter where the ball is going.
His frame is tiny and more reminiscent of, say, a tennis player than a football player. But he’s ripped for his size and if he plays it smart a la Marvin Harrison or Desean Jackson or Lynn Swann and just get down, he can be fine.
If you trade down and end up with an extra one and two to drop to, say, Carolina, that’s understandable to a degree on paper. But if Smith ends up a Hall of Famer you might wince that you essentially traded him away.
