The Facts: Collins proved to be the biggest surprise of the Ravens this season, going from the practice squad in Week 1 to the NFL's 11th-leading rusher. But HC John Harbaugh was noncommittal when asked whether Collins earned the right to be the starter for next season or if Baltimore will look to upgrade. "I'm looking to upgrade everything. You know that's how I'm going to answer the question," Harbaugh said. "Alex Collins has proven the fact that he can be a very good back in this league."

Diehards Line: Collins became the Ravens' offensive most valuable player, producing big plays with his aggressive running and elusiveness. But Collins isn't seen as a workhorse back by Baltimore. The Ravens never gave him the ball more than 20 times in a game because they didn't want to wear down a smaller frame back like Collins. There are also other issues with ball security (four fumbles) and catching the ball (three drops). Collins proved he could be the lead back in a committee situation like last season, when Buck Allen and Danny Woodhead were contributors. While Terrance West isn't expected to return as a free agent, this group will welcome back Kenneth Dixon, who suffered a season-ending knee injury before the start of training camp in addition to getting suspended twice. "Dixon should be right in that conversation," Harbaugh said. The Ravens feel much better about their running game than a year ago at this time. Baltimore's ground game went from being No. 28 in 2016 to No. 11 last year. But the Ravens haven't ruled out adding someone else to improve the rushing attack even more. "We're going to look to have the best running back group we can," Harbaugh said. "If that means we add a guy, I'm all for it."
