Ours werent positioned based per se. In the offseason you ran 3 40s and got your avg time. FOr the conditioning test you had to run ten 40s in your avg time plus a buffer to account for conditioning. The buffer was based on your position, OL got more WRs less. So a bigger LB would still have to run his 40s based on his time plus position buffer.
Im not sure how Wash does theirs, only heard it was 300 yard shuttle.
