No competent team makes decisions based solely on the Combine. It's a data point that gets combined with college game tape, private workouts, and some other special events like the Senior Bowl. Also, a significant number of players who end up getting drafted or signed as Undrafted Free Agents don't go to the Combine.
I didn't make that assertion. I was simply pointing out that the NFL has a set of skills tests that aren't football. Further, the effectiveness of the combine is as widely debated as the effectiveness of algorithm questions.
