Highlight videos can be very convincing but they generally do not give an accurate picture of what a player is. A DT taken late in the 7th round is probably a project at best. It's possible he turns out to be Leon Lett or Jay Ratliff, but more likely he is a Colston Weatherington or John NIx.
Having said that, the traits they claim Akingbesote has are the traits that can turn a 7th round pick into a good player in the NFL. It starts with strength but eye are also important. Sometimes when you watch Mazi you can see he gets caught up in the battle with the offensive line and forgets to locate the ball. Maybe NFL coaching can turn Akingbesote into a Jay Ratliff, but I still see him as a dark horse in the DT battle.
