Like every team, the Patriots suffered their share of injuries over the course of the 2012 season. Here’s a look at four guys who went down relatively early, and who could play a sizable role in the fortunes of the 2013 team:
Linebacker Dane Fletcher : The 26-year-old inside linebacker was an undrafted free agent who made the 53-man roster out of Montana State in 2010. The 6-foot-2, 244-pounder, who was a defensive end in college was able to carve out on impressive career for himself in his first two seasons in the league, moving from core special teamer to backup linebacker in relatively short order. But a thumb injury slowed him in 2011, and he tore the ACL in his left knee in an August preseason game against the Saints. The knee injury left him on injured reserve for the season, but as long as he recovers, he should be expected to be in the mix as an inside linebacker and special teamer in 2013.
Kick returner/running back Jeff Demps: The former Olympic sprinter showed up relatively late this summer, and left the Patriots with an interesting personnel decision — place him on IR (with the possibility he could return, thanks to the new DFR roster loophole) or have him occupy a roster spot until he was ready to go. The Patriots chose the former, and ended up putting tight end Visanthe Shiancoe on IR (designated for return) while leaving the 23-year-old Demps on the sidelines for the year. That’s a decision the Patriots would probably like to have back, as the team used the DFR-IR designation on Shiancoe before cutting him loose late in the season. (In that same stretch, the Patriots continued to struggle to find consistency in the return game.) Meanwhile, the 5-foot-7. 175-pound Demps got time to get up to speed in the New England system, essentially taking a redshirt season while learning about life in the NFL. Look for him to play a major role on special teams next season, as well as a possible dynamic new wrinkle at running back.
Tight end Jake Ballard: Hey, another tight end. Why not? The 25-year-old Ballard, who suffered a torn ACL in his left knee in Super Bowl  XLVI against the Patriots while playing for New York, was acquired this past summer by the Patriots (he was signed off waivers from the Giants , much to the consternation of New York coach Tom Coughlin ). Undrafted out of Ohio State in 2010, he turned himself into a effective downfield threat in 2011 with the Giants (38 receptions for 604 yards and four touchdowns), and could provide the same sort of presence in 2013 with the Patriots. The 6-foot-6, 275-pound Ballard compares with Rob Gronkowski  in his bulk and his overall playing style, and the idea of deploying a three-tight end set with Ballard, Gronkowski and Aaron Hernandez  would be an intriguing matchup problem for opposing defensive coordinators. Figures to weigh heavily in the Patriots’ plans for 2013.
Cornerback Ras-I Dowling: Dowling, who was the 33rd overall pick of the 2011 daft, has seen his two-year career with the Patriots has been marked by injury. After a strong opening to his rookie year in 2011 where he started his first two games as a professional, he landed on season-ending injured reserve on Oct. 29 because he needed hip surgery. And 2012 started poorly when he suffered a hamstring injury early in camp and missed nearly three weeks. As a result, he slipped down the depth chart, and began the season as a nickel back. This past season, he made it all the way to late October before suffering a thigh injury in an overtime win over the Jets, which sent him to IR again. When he’s been healthy, the 24-year-old has been an intriguing physical presence in the secondary — at 6-foot-1 and 210-pounds, he brings a size that New England had been lacking in the defensive backfield for several years, at least until Aqib Talib  came along. But Dowling, who had struggled with injury in college, has to prove that he can stay healthy for an entire season before the Patriots start to lean on him seriously. This will be a key offseason for the youngster out of Virginia.
