seevee,
here is the problem. You mention one defensive player in that group.
Our defense will be bale to stay with your wr's; your defense will not be able to reciproate.
Besides, college football is littered with claims of 4.3/40's; but msteriously, when those same players perform for official nfl combines, those speeds don't exist.
But on Smith's run, I saw that with my own two eyes: a very fast SEC defense had no answer for him.
Have a nice day.
