Luck and Darrius Heyward-Bey watch practice during OTAs.
Reggie Wayne (No. 87)
The 33-year-old receiver showed that he's still got everything he needs to be successful last season. Wayne was Pro Football Focus' third best receiver in 2012, and was the Colts' most dependable offensive weapon throughout the season. While Wayne struggled in the end zone, most of the struggles were because of Luck and the offense's struggles in general, not a fault of Wayne. With a more efficient offense, that hopefully uses Wayne in the slot as much as Arians' did, the grizzled vet should see high numbers once again this season.
Darrius Heyward-Bey (No. 81)
The former seventh-overall draft pick struggled for the past four years in Oakland, although the revolving door at both quarterback and head coach definitely had a negative effect on his development. Heyward-Bey certainly has the size (6'2" and 210 pounds) and speed (4.3 40 yard dash as a rookie), but his route running and occasional drops have hampered his production thus far.
T.Y. Hilton (No. 13)
The Colts' most promising big-play weapon burst onto the scene as a rookie with a yards-per-reception of 17.2, the 10th highest mark in Colts' history. Hilton struggled with drops and inconsistent route running in 2012, but he showed a strong connection with Andrew Luck that led to one of the best rookie wide receiver seasons since 2000. He should continue to be a key part of the Colts' downfield attack in 2013.
LaVon Brazill (No. 15)
Recent news of Brazill's four-game suspension due to a substance abuse violation has certainly put a damper on his development. Brazill was lined up to be the Colts' fourth wide receiver this year, and one of the best long-term depth options. Brazill shouldn't be cut over this, but he will need to have a strong training camp to earn back the trust of the coaches.
Nathan Palmer (No. 10)
Palmer made it onto the field for several plays last season, but was unable to make any real impact, dropping the ball on his one chance to score against the Packers. However, the Colts like Palmer, and he has the inside track on filling Brazill's spot while he is suspended.
Griff Whalen (No. 17)
Colts fans fell in love with Whalen last year when he showed off a chemistry with Luck leftover from their relationship at Stanford. Whalen, despite having limited physical traits, has good instincts finding soft spots in coverage, and could develop into a solid slot receiver. Unfortunately, a foot injury in preseason kept him on injured reserve, and he comes into his sophomore season with no real NFL experience. Fortunately, his previous experience in Pep Hamilton's offense should give him an edge going into training camp.
Jeremy Kelley (No. 84)
The Colts' lack of size was a severe deficiency last season, and one possible fix for that was the signing of former CFL receiver Jeremy Kelley. Kelley is 6'6", 235 pounds, easily the biggest receiver on the Colts roster. He hasn't shown much in OTAs, so he'll need to have a strong training camp to earn a roster spot.
Jabin Sambrano (No. 16)
Indianapolis signed Sambrano as an undrafted free agent last season, but cut him a couple weeks into the regular season. Sambrano was eventually picked up by the Buccaneers and put on the practice squad, and he was offered a future contract by the Colts in January. Sambrano has some history with the Colts, but didn't impress last year and is currently behind Whalen and Palmer for the final spot on the 53-man roster.
Rodrick Rumble (No. 11)
Rumble is another one of the Colts' bigger options at 6'2", 207 pounds. Rumble graduated from Idaho State this past year as the all-time leader in receptions and yards. He should simply be a camp body, but will be aiming for a roster spot.
Lanear Sampson (No. 14)
Like Rumble, Sampson was signed by the Colts as an undrafted free agent and will be battling for one of the final spots on the Colts' 53-man roster. Sampson is an explosive player with potential to be a solid deep threat, but he's a long shot to make the roster.
