Martin went off last season for 1,454 yards and 11 rushing touchdowns. He also had 472 receiving yards and one receiving TD. So yeah, you can say he had a pretty good season.
Martin definitely set the bar high in his first season, which makes it hard to match any other season. However, he clearly has a lot of talent and it helps that Josh Freeman is a solid NFL quarterback.
Freeman doing work through the air takes pressure off of the running game and vice versa with Martin in the running game. Freeman threw for 4,065 yards and 27 touchdowns last season. However, he also threw 17 interceptions and only completed 54.8 percent of his passes.
Tampa Bay finished with a 7-9 record last season, but they have great players at key positions, which is huge for any NFL team.
Martin is certainly capable of putting up better stats in the upcoming season, but who knows if he will get as many carriers and all of that fun stuff. However, if he does get more carries, people can expect him to be one of the top backs. He already finished fifth in the league in rushing yards and tied for fifth in rushing touchdowns in his rookie season, so that case has basically already been made.
It will be interesting to see if he can match his rookie stats or exceed them, but with the talent he has, that is very likely to happen.
