MARTINSVILLE, N.J. (AP) — More than 300 NFL hopefuls will be poked, prodded and tested perhaps more than any other job applicant at the annual scouting combine in Indianapolis this week.

One result can make all the difference.

A slower-than-expected time in the 40-yard dash can see a prospect (Maurice Clarett, Tom Brady) tumble in the draft. An impressive all-around performance can help a player (Mike Mamula) rocket up the board.

Millions of dollars are at stake and even careers. Some players won’t get a call on draft day. Others will have to pursue their dream in the CFL or Arena League.

That’s why college players across the country spend weeks preparing for the combine at training centers such as TEST Parisi Football Academy.
