I have a player that has the following stats

Positioning 3 Tackling 1 Punting 5
Vision 4 Blocking 3 Speed 16
Intelligence 20 Passing 4 Strength 11
Footwork 5 Catching 2 Agility 4
Carrying 7 Kicking 6 Stamina 8

What position would you player him? He is coming up as a CB

agreed, or even a WR, TE, or possibly RB ....

His intelligence of 20 is very nice, if he has high consistency he is a good nice player...

would be tempted to see where his Speed caps at, because WR, CB, or FS would all be nice with that intelligence (i know others have different views on intelligence)

Running back for sure. I don't think you can waste a player with good speed, decent footwork, and good stamina and carrying.
