Why do people keep returning to this same complaint? For crying out loud, you don't even make the same gripes. If Maroney's problems were truly as legion as you all combine to make it seem, he'd never have made it out of Pee Wee football, nevermind ever getting to the NFL.
Synovia has already effectively destroyed most of the whining complaints on a couple of other threads, so I don't want to go down the data side of things. Instead, I'll point out some other 'issues', and interject some other thoughts and notions.
1.) Maroney in the game tends to tip off the opponent that it's a running play. He's not in on passing situations and the team doesn't throw him the ball enough. Opponents are allowed to key on Maroney in ways that they can't key on the other running backs. Maroney still gets his yards.
2.) In his two 'full' seasons, Maroney has had a higher YPC than Dillon and had the same YPC as Morris.
3.) People complaining about his durability should realize that, while Maroney has only played 16 of 32 regular season games over the past 2 seasons, Morris has only played in 19 of those 32 games.
4.) Joseph Addai, the runner Maroney was most often compared to when he came into the league, has seen his game decline in each of his 3 seasons in the NFL. He's 2 years older than Maroney, has taken a lot more pounding in the NFL, and may already be past his prime.
5.) Maurice Jones-Drew, the other runner generally compared to Maroney, has also seen his YPC decline every year he's been in the NFL. He was a human bowling ball during his rookie year. Last year, he was a relatively pedestrian player with a 4.2 YPC. He's about the same age as Maroney, and I don't think he's in decline, but it's important to note that his offensive line was devestated last year and his numbers went down. You know, like the Maroney situation in New England before he went on IR.
6.) I expect Fred Taylor to be a great sounding board for Maroney, since he had to deal with the same sort of nonsense from the Jaguars fans when he was a younger player.
7.) I hope that the new O.C. (whomever it may be) will use Maroney to catch more passes, will allow for more sweeps and more one-cut runs, and will allow Maroney to develop a full game on the field.
