With the Pittsburgh Steelers rookie minicamp opening on Friday, the team’s crop of rookies and undrafted free agents will get their first taste of NFL action. So will the team’s minicamp invitees, a group that includes a lot of intriguing names. The Steelers have three roster spots open, meaning there’s a good chance at least one of the guys who was a non-roster invite to minicamp gets signed to a contract next week when the Steelers likely get their roster up to 90 players. I’ll take a look at three players, excluding any XFL invitees, who have the best chance to get a contract from Pittsburgh next week.
