With minicamp behind us, let's break down theIndianapolis Colts'roster through a different lens.In this series, we will be going position-by-position and placing each player into one of three categories -- are they a lock to make the team, likely to make the team, or on the bubble and fighting for a role?What this exercise can do is help bring into focus how many roster spots are actually available this summer, along with highlighting who may be on the outside and looking in.Up next are the wide receivers.Roster locks (3): Alec Pierce, Josh Downs, Ashton DulinPierce and Downs will lead the way at wide receiver, and Dulin appears to be the front-runner for the Colts' WR3 role. However, even if Dulin doesn't win that job, we know he will be on the team. Over the years, he has been a core special teams contributor and a willing blocker in the run game, which is quite valuable for Shane Steichen.Probably make the team (3): Nick Westbrook-Ikhine, Deion Burks, Anthony GouldI would expect these three to be on the roster, but it's not a 100% lock either. If needed, the Colts can get out of Westbrook-Ikhine's contract fairly easily. Gould has handled return duties and is a secondary option out of the slot, but those are roles Burks -- or others -- could potentially handle as well. Seventh-round picks, like Burks, are never quite guaranteed to make the team either. In recent drafts, we've seen Chris Ballard release a few draft picks prior to their first seasons.On the bubble (6): Laquon Treadwell, Raylen Sharpe, Eli Pancol, Coleman Owen, EJ Horton, Sahmir HagansThe player to watch here is Treadwell. He could possibly end up seeing playing time in that third wide receiver role or provide depth. However, as we've seen the past few years, Treadwell spending time on the practice squad is in play as well.This article originally appeared on Colts Wire: Colts 53-man roster: Locks and bubble players at wide receiver
