For me, Tillman is the more complete WR prospect between he and Hyatt. All will depend on where they end up.
If Hyatt goes somewhere that can scheme him open with a QB that can throw deep, watch out.
I think Ced has more versatility in terms of he can be successful in more different systems. The main knock on him is "he’s a step slow", to me 4.55 pretty much nixes that. If he cleans up some minor things in his route running, he could become a very dangerous weapon.
