i thought maroney's highlights in college were very impressive, but i have a lot of gaps in my knowledge of his entire body of work...
at his best, though, even though i agree he gets to high speed quickly (if not top speed), i think he has the kind of stride that gets even faster the further he gets downfield... when he was in the open, he had the speed to explode past DBs even in the open field...
he also had some other good traits in my limited, abbreviated look at him (ie - highlights)...
he looked to already haved advanced ability for young RB (some never get it) to be patient & let blocking develope... also seemingly good vision & instincts which are also highly correlated to success if RBs have all the other requisite physical attributes, triangle numbers, etc...
not sure what distribution of carries will be (probably belichick isn't yet), but i think dillon will get bulk of carries if he plays like he did in 2004 (captain obvious observation)... but if he has slight drop & maroney continues to play as well as he looked in debut, i could see close to a split with maroney maybe even getting more than half later in the season...
i think it is more contingent on what dillon does than anything else, & agree the fact that OL is much healthier (at this point anyway) than last year should be viewed as a positive for dillon... of course, it could be for maroney, too.
