INDIANAPOLIS – The first offseason event has come and gone with some substantial news on a league-wide, and Colts-specific, level.

While fans enjoy seeing how prospects graded during on-the-field drills, much can be learned in listening to the 48 NFL coaches and general managers who spoke in Indianapolis.

Here were five things learned in Indianapolis that will impact the rest of the Colts offseason:

Where To Turn At Safety?[

The release of LaRon Landy came in the days leading up to the Combine](http://www.colts.com/news/article-1/Colts-Combine-Notes-Mike-Adams-Back-Other-Major-Offseason-Needs/56240109-9d8c-4f7f-b63e-5552386c5f9b), pushing safety up the offseason shopping cart list. That cart down the draft aisle looks a little bare on the first few shelves though. Several draft prospects talked about how they only have one safety in the first two rounds of their mock drafts. The Colts are hoping to re-sign Mike Adams and you have to think the team will seriously look for another starting safety in free agency before the attention shifts to the draft.Defensive Line Depth Lacking

Monday was the final day of the NFL Combine but the biggest news for the Colts came further north at the Indiana Farm Bureau Football Center. The Colts released Ricky Jean Francois, a guy who started 13 games last season. With Cory Redding considering retirement for a second straight season, the Colts could be without their top defensive line snap contributors from 2014 when free agency arrives. The interior defensive line looks to be a strength in the draft, especially in the early rounds.

Talented Skill Groups In 2015 Draft?

Our look around the league at the Combine focuses on the depth of the 2015 draft class. While defensive line and offensive tackle got some mention as deep position groups in 2015, the ball carriers and pass catchers stole the show. In Melvin Gordon and Todd Gurley, you have two running backs who are in virtually everyone’s mock drafts. The running back group has plenty of top-end talent. At wide receiver, some NFL personnel people believe the 2015 class could challenge the absurd numbers put up by last year's haul.Pass Rush Need[

With an uncertain timetable](http://www.colts.com/news/article-1/Colts-Combine-Notes-Mike-Adams-Back-Other-Major-Offseason-Needs/56240109-9d8c-4f7f-b63e-5552386c5f9b) regarding the rehab process of Robert Mathis, pass rush probably moves up the need scale. Both Ryan Grigson and Chuck Pagano talked about the importance of always having a stable of edge rushers. This year’s group of pass rushers put up some impressive numbers during the Combine and General Manager’s seem to be pleased with this year’s crop. Whether it's through free agency or in the draft, the Colts are in all likelihood looking to add another edge presence.Free Agency On The Horizon

We are two weeks away from the madness that is NFL free agency. That first Tuesday afternoon of free agency is filled with teams plucking the top available talent. The Colts will have plenty of cap space to operate with, however they would like. Names like Ndamukong Suh (Lions) and Frank Gore (49ers) have been popular ones for fans to speculate. At the Combine though, those players' GM's did not hold back in their hope to retain the Pro Bowl free agents.
