Indianapolis Colts general manager Ryan Grigson will likely be watching one event in particular at the NFL Scouting Combine.

Grigson is entering his fourth draft with the Colts, and has put an emphasis on the 40-yard dash when evaluating prospects.

"The actual interview with the player we feel is incredibly important. It is where you find out how the player fits in so many ways from primarily a mental and character standpoint," Grigson said to Colts.com's Kevin Bowen about the draft evaluation process.

"The other I would say is the 40 time, not that it is or isn't the reason to draft a guy, but at the end of the day it helps you assign proper market value to the player. Especially at those skill positions."

In his first draft, Grigson and the Colts selected T.Y. Hilton in the third round, arguably one of the fastest wide receivers in the league.

Indianapolis apparently views speed as the biggest asset in the draft, and it'll be interesting to see how their draft board correlates with some of the top performers at the combine.
