In this Eagles website video, Stanley Havili says that he’s put on 25 lbs since he came to the Eagles, up from 225 to over 245 lbs. When he was drafted in 2011, Havili looked more like a large running back than a true fullback. Perhaps the added weight will help him as a blocker.
I mentioned Havili when I discussed the fullback position a couple months back. His versatility as a runner and pass catcher could make him a more valuable contributor than Owen Schmitt. But the irony is that as the second tight end eclipses the fullback in most situations, that player’s ability to excel in other areas actually becomes less important. If the fullback is almost exclusively going to play in short yardage, I-formation sets, it would be better for him to specialize in actual blocking.
