Missouri kicks off its camp season on Wednesday with a one-day recruiting camp in Springfield, followed by a similar workout in St. Louis, Kansas City and then two team-camp sessions over the next two weeks. Before PowerMizzou.com brings you all the action live from the camps, we're giving in-depth previews -- the top recruits attending, and what they need to show to the Tigers' staff. Today, we'll start in Springfield.

Why he's big: Hamilton has yet to pull in an offer, but he's been firmly on the radar of schools across the Midwest, including many Big 12 programs. There's not a ton of talent surrounding him at Beggs, but his athleticism stands out after one viewing of his highlight tape. He has the potential to play quarterback, receiver or defensive back in college.

What he needs to show the coaches: Missouri has shown interest in Hamilton for the past few months, but it's clear he's not near the top of the Tigers' early wish-list at quarterback. If Hamilton wants to maximize his chances of receiving an offer down the road, he'll have to display that reknowned athleticism. Surely, he'll work out as a quarterback, receiver and safety on Wednesday, and if he runs well and excels in multiple position drills, he could get a late offer from Missouri.

Why he's big: Harger is the second of three Oklahoma quarterbacks Missouri is showing some interest in (the final being Owasso (OK) QB Kason Key, who will attend a later Missouri camp). Harger is known for his quick release and above-average arm, and runs a spread offense at his high school. Like Hamilton, Harger is receiving interest from schools around the Midwest and Big 12.

What he needs to show the coaches: Harger can sling the ball all over the field. The bigger question is if he's athletic enough to run Missouri's offense, which excels with mobile quarterbacks. It's unlikely he picks up an offer after camp; however, a strong performance will keep him on Missouri's radar should other options turn elsewhere.

Why he's big: Green-Beckham is the No. 1-overall player in the nation for 2012, in case you missed it. He's a game-changing receiver, and has the potential to step in, start and star from Day 1 at nearly any college across the nation. He's in Missouri's backyard, which makes him even bigger for the Tigers' future.

What he needs to show the coaches: Nothing. Green-Beckham has held a verbal offer from Missouri since his freshman year. Last year, he missed this camp because he had to make up tests that he missed while away at the Missouri state track and field championships. This year, according to his father and coach John Beckham, he'll be in attendance.
