I may be incorrect but I believe intelligence is 'overall' but different positions utilise it in different ways.
Speed is based on the speed rating and weight not position ie DT and WR both 100 speed and 300 pounds = same speed but WR's are usually much lighter and therefore faster.
I am still little hazy on strength but i think two players same stats same strength then the 300 pound DT is going to knock a 190 pound WR into next week most of the time. But there are a lot of parameters in each position that will affect how well a player will utilise their physical characteristics.
