Deion Sanders was speculating it was (at least partially) because of the differences in the warmup routines of the two groups. The WRs were running routes, and were much looser prior to running their 40s.
The DBs were huddled in the end zone, and some, but not all, were stretching. None of them were running any sprints.
Of course Deion also thought the DBs would get better times on their second run, and most didn't.
