I think I've figured it out. It took me a couple of practices and talking to a couple of people, but it is clear to me why the Dolphins applied the stiff-arm to fullback Vonta Leach late last week.

It's just that the Dolphins are going to use a one-back look with four pass-catchers (three receivers and a tight end) or an I-formation look with the tight end as the lead blocker look going forward. And none of that leaves a lot of room for a fullback on the roster.

It makes sense, really.

When you consider the Dolphins have three starting-caliber and high priced receivers in Mike Wallace, Brian Hartline and Brandon Gibson on the team, it makes sense to get them on the field as much as possible. When you consider Dustin Keller is an experienced and solid tight end and the Dolphins are heavily invested in the position with Charles Clay, Dion Sims, Kyle Miller and Michael Egnew, it makes sense to have an extra roster spot not occupied by a fullback and instead used on an extra tight end.

Voila, mystery solved.

I remind you the Dolphins still have two fullbacks on the roster: Jorvorskie Lane and Evan Rodriguez. But neither has gotten even one snap with the first or second-team offense in two days of camp that I've noticed. Both are in a deserate fight to merely make the team. I don't like their chances.

With the two tight end sets and QB read options, it's safe to say that fullbacks are a dying breed in the NFL

he wasn't necessarily mediocre either.

17th out of 25 FBs is pretty mediocre.

I didn't realize he did that bad statistically. I remember the hype surrounding him earlier in the season, must have all went down hill from there for him.
