FSU is looking to replace significant contributors to one of the most productive offenses in the history of college football.

The Seminoles scored 723 points, an all-time record, during their 2013 championship season. FSU has plenty of firepower returning: QB Jameis Winston looks to repeat as the Heisman Trophy winner and will have proven weapons around him like WR Rashad Greene, TE Nick O’Leary and RB Karlos Williams.

While the Seminoles return seven players on offense, they must find a way to make up for the departures of impact players like RBs Devonta Freeman and James Wilder Jr., and WRs Kelvin Benjamin and Kenny Shaw.

FSU loses players that scored 48 of the team’s 86 offensive touchdowns last season. How do the Seminoles go about compensating for those losses? They begin searching for answers in spring practice, which begins March 19.

The Chopping Block previews some of the key areas to watch heading into the spring starting with the running backs.

Running Game

This is arguably the most interesting group to watch in spring practice. Based on raw talent alone, the Seminoles could be better in the backfield this season, or at least more dynamic.

Both Freeman and Wilder opted to forgo their senior seasons and enter the NFL Draft.

Freeman was FSU’s workhorse, rushing for 1,016 yards and 14 touchdowns on 173 carries last season. While there wasn’t much flash to his game, Freeman brought additional value by being a reliable receiver out of the backfield and a strong blocker in pass protection.

Wilder was dinged up for a good chunk of the season. As a result, he became more of a goal-line specialist than anything else, rushing for 563 yards and eight touchdowns on 81 attempts.

FSU coach Jimbo Fisher tends to go with a by-committee approach at RB, which is beneficial in a situation like this. Karlos Williams was moved from DB to RB at the start of the season and was able to slowly adjust to the new position. He was easily FSU’s most explosive back by the end of the season, averaging eight yards per carry (730 yards, 91 carries). He scored a touchdown every nine times he touched the ball.

Williams figures to be FSU’s feature back this upcoming season. The potential is there for him to top Freeman’s production. After all, Williams is bigger, stronger and faster than Freeman. However, the intangibles Freeman brought to the table will be difficult to supplant and Williams’ adjustment will be learning how to become a back that carries the ball 20 yards a game. There is more of a mental and physical toll that comes with that role. He will be asked to do a lot more this upcoming season and must leave the spring with a firm grasp of the playbook.

The other question at RB this spring is who will step up behind Williams to add depth?

The contenders: Rising sophomore Mario Pender, rising sophomore Ryan Green and incoming freshman Dalvin Cook.

“All four of those guys jump out at me, they really do,” Fisher said of his running backs.

Green is the only player of the trio that touched the ball last season (33 carries, 163 yards) but he may not be the best bet to end the spring at No. 2 on the depth chart. He is “explosive”, according to Fisher, but so is Pender. Pender, who was academically ineligible last season, has impressed Fisher in offseason workouts and has a little more girth to handle running between the tackles.
