The New Orleans Saints are concluding a three-day minicamp on Thursday with three former Alabama players seeking to define their roles on the team for the 2014 season. Mark Ingram, the 2009 Heisman Trophy winner, is competing at running back with five players who started their NFL lives as undrafted free agents. Vinnie Sunseri is practicing as a second-team safety after being selected in the fifth round of the 2014 NFL Draft. Defensive lineman Brandon Deaderick has been busier at minicamp than would be expected for a player signed by the Saints last week.
