Actually, I looked back at the San Diego game during maroney's great run and he had a ton of 2,3,4,5 yard runs mixed into one of his best games.
All running backs, including Maroney, have an awful lot of those.
I actually wasn't even talking about Maroney, but in general about the relative usefulness of a north south runner to a home run hitter.
And that's a valid and worthwhile discussion. Home run hitters tend to be characterized by sub-50% success rates, and I agree that those guys don't do your offense any favors. They're just as likely to kill a drive as they are to move the chains, and that's obviously not what you want your ground game to do.
The disconnect between us, clearly, is that you think that Maroney falls into that group. I used to think the same thing, but I can clearly, objectively, and with 100% certainty (with a mountain of supporting evidence) tell you that he does not fall into that category. Maroney, in fact, is--when healthy--one of the best RBs in the league at 'hitting for average' (dunno what else to call it, so might as well stick with the baseball analogies'.
In fact, Football Outsiders abbreviates success rate as RBBA, for running back batting average, because that's what it is. In general, they've found that running backs with over 100 carries have success rates that almost always fall between 36% (the absolute worst) and 60% (the absolute best), so if you want to keep up with the baseball reference you can subtract .200 off of a RB's success rate to get his 'batting average'.
In 2007, Maroney had a 58% success rate: a .380 batting average, and it was the best in the entire NFL. Brandon Jacobs came in right behind him at .370. Fred Taylor (and this was in a really good year for him) hit .250, which was about league-average, before falling to an abysmal .210 in 2008. Morris 'hit' .290.
So yeah, in the hypothetical, I absolutely agree with you- you want some 'home run' potential in your running backs, which Maroney has, but you absolutely need a 'singles hitter' too. The point where we differ, I guess, is in that Maroney not only
is a singles hitter, but he's one of the better (or even best) ones in the NFL.
Anyway, I think Maroney is all pro caliber if he runs like he did in the San Diego game, leave it at that. He's had a lot of injuries, I'm not down on him. I just think BJ can be a decent utility runner. He's young and could team with Maroney, or back up like a Patrick Pass. No room for him this year, but they can juggle for a kid with the right attitude.
Attitude is the key too, because all these available backs that are always around as good as him, never seem to work out for much when we need one, and we've had awful RB injury situations. I like to see a kid force his way onto a roster when there's no real need. that's what preseason is all about for me.
I think we've found some common ground on this one. I agree that someone like BJGE is an asset, but I look at the guys on the bubble, and the question, to me, becomes which of these guys do you take: Ninkovich, Crable, Alexander, BJGE, Ventrone, McGowan, etc. Realistically, of that group that I just named, it's unlikely that more than one of them will make the team. Maybe two. As much as I like BJGE, I'd rather see someone like Ninkovich (who has showed some versatility at areas of need, and some real talent off the edge) or McGowan (who I think can be our primary backup safety while Chung learns the ropes).
It has less to do with not liking BJGE, and more to do with simply valuing some other guys higher. Namely guys who don't play the most easily replaceable position in the NFL (which RB has been statistically shown to be), and who can step in and contribute right away, with or without injuries.
