INDIANAPOLIS -- Alshon Jeffery, DeSean Jackson and Pierre Garcon are some of the top receivers that will be on free-agent market once the period begins on March 9.

What do any of those players have to do with the Indianapolis Colts? A lot, because there's no such thing as having too many skill position players for quarterback Andrew Luck to turn to.

This isn't a situation where the Colts need to use their first-round pick on an offensive player or make it a focus once free agency starts next week.

But when it comes to receiver, the Colts might want to take a look at some of the free agents available because they might not be as set at that position as it seems on paper. The issue isn't with T.Y. Hilton. He led the NFL in receiving yards with 1,448 last season.

There could be some questions after him, though.

Donte Moncrief is the perfect possession receiver (see his back-shoulder touchdown catch at Green Bay in Week 9 last season) for Luck because he has the combination of size and speed.

The issue is Moncrief's durability. He missed seven games with a shoulder injury last season after not missing game in his first two seasons.

Phillip Dorsett has yet to take off the way the Colts envisioned when they decided to select the University of Miami speedster in the first round in 2015. Dorsett has 51 catches, 753 yards and three touchdowns in 26 games over the past two season.

Tight end Jack Doyle was second to Hilton in receptions (59) and yards (584) last season.

Indianapolis will have around $60 million in salary-cap space to work with during free agency.

The Chicago Bears decided against using their franchise tag on Jeffery on Monday, according to ESPN Bears reporter Jeff Dickerson. The 6-foot-3 Jeffery had 174 receptions for 2,554 yards and 17 touchdowns during the 2013-14 seasons. Injuries caused him to miss seven games in 2015. Jeffery had 821 yards and two touchdowns despite missing four games due to suspension last season.

Garcon is a name the Colts are familiar with. He spent the first four seasons of his career in Indianapolis before signing with the Washington Redskins in 2012. Garcon led the Redskins with 79 receptions and 1,041 yards last season. He's also durable, as he hasn't missed a game since 2012. A possible issue with Garcon, outside of money, is that he'll be 31 years old before the season starts.

The speedy Jackson has five seasons of at least 1,000 yards in his nine years in the NFL, including 1,005 yards last season. Jackson will also be 31 years old later this year.
