I doubt you are the only one but you and many others need to keep in mind that it wasn't just the players and their "game speed". People say this about Armani Reeves.
So I ask you, when you have Roby who ran a sub 4.4 at the Combine, Doran Grant who has 4.4 speed and Reeves who was a highly regarded recruit all looking like
Last year he was constantly getting beat on comeback routes where he couldn't react quick enough.
do you really think its all those players fault and they ALL suck, or could it be that the system was a mess and ALL of them were put in bad positions to fail no matter how good they are.
I believe Grant and Reeves are very talented and can succeed at the collegiate level. They just need the right defensive system to allow them to do well. Its not a coincidence that NOW Eli Apple is starting to look like the stud we expected, because he is finally put in the right place for his skill set. Soft Zone can make any corner look bad, especially if there isn't any blitzing: like a 3 man rush, 10 yard cushion zone!
