The celebration of a BCS championship victory is in the rearview mirror for Florida State, and Jimbo Fisher, Jameis Winston and Co. have already turned their attention toward adding another trophy in 2014. So as Florida State preps for spring practice, we’re digging into the biggest questions, position battles and storylines facing the defending national champs.

This week, we’ll look at the five position groups with the biggest question marks looming in advance of spring practice.

Previously, we reviewed the running backs and linebackers.

Next up: Receivers

Projected starters: Rashad Greene (Sr.), Christian Green (RS Sr.), Kermit Whitfield (So.).

Greene’s decision to return for his senior season was crucial for Florida State. He has led the Seminoles in receiving each of his three years in Tallahassee, and he was Winston’s most reliable target in 2013, catching 76 passes (second most in school history) for 1,128 yards. The problem is, there’s not much in the way of established talent surrounding Greene. Whitfield figures to be a suitable replacement for Kenny Shaw in the slot, and he showed ample gamebreaking ability in the return game in 2013. Finding someone to step in for the departed Kelvin Benjamin, however, remains a far bigger question mark.

Strength in numbers: Jarred Haggins (RS Sr.), Jesus Wilson (So.), Isaiah Jones (So.).

Haggins’ return at least provides some veteran depth for a group that has little in the way of experience, but coming off a season-ending knee injury, Haggins hasn’t caught a pass since the 2012 ACC title game. Wilson and Jones each got a taste of action last season, but both have plenty of growing still to do.

New on the scene: Travis Rudolph (Fr.), Ermon Lane (Fr.), Ja'Von Harrison (Fr.).

Florida State might have landed the best recruiting class at wide receiver in the nation, with Rudolph, Lane and Harrison all making the ESPN 300. It wouldn’t be a shock if all three freshmen make an instant impact, and given the lack of depth at the position currently on the roster, all will surely get a chance to prove they deserve playing time.

What to watch: FSU fans won’t get a glimpse of the super trio of freshmen until fall camp, which puts the spring focus squarely on last year’s class. It’s not uncommon for a receiver to make a big leap developmentally from Year 1 to Year 2, and Wilson and Jones certainly have the talent to do so. Whitfield is electric, but it remains to be seen if he can use his world-class speed as well at receiver as he did in the return game. Green is an intriguing figure this spring, too. After a solid 2011 season, he’s all but disappeared from the offense the past two years, and he could find himself behind the youngsters on the depth chart in 2014, too, if he doesn’t turn in a solid spring.
