Actually I think he nailed it in this article ... those would be my top 5 in that order. Porter, obviously, was our most dominant player last season. Bell was definitely up there, but any rookie LT that allows that few sacks has gotta be put in the dominant category, but then add the strength he showed in the running game and it becomes truly impressive. With a year under his belt, I expect Long to really dominated far more this season than last.
Bell has to be up there somewhere. He didn't make enough interceptions to rank in the top two, but he was a real stalwart of our defense, particularly considering the weak ILB's in front of him and the fact that he held a suspect secondary together.
I'm a big fan of Ricky Williams, but he's clearly not the player he once was. This is Ronnie Brown's team and his ability both in the base offense and in opening up the wildcat justifies his pick. I'd say that spots 4 and 5 (Jason Taylor) are a bit up in the air, with Chad Pennington a deserving member of the top 5 somewhere.
Personally, I'm a huge fan of Jason Taylor and I suspect we will see him do some really dominant things back in Miami with a full dance-less pre-season and not being worn down as much during the season because of playing every down. As an edge rusher he still has all of the quickness, speed, strength, length, and explosion needed to dominate against either tackle.
I think Chad Pennington would be #6 for me, because while he was excellent, his lack of a consistent deep ball prevents me from calling him dominant. Our running game suffers because opposing defenses can afford to let our speed guys like Ginn go single-covered. It's not so much that they can run with Ginn as they know Pennington can't get him the ball by the time Ginn beats his man deep, so while we may hit one long, we may also get it picked off, and Pennington is extremely risk-adverse as a QB, so even if the gamble is a good one, Pennington is likely to check down to a TE or RB than he is to pull the trigger on that deep ball. Most of Pennington's long passes are run-after-the-catch type long plays. For that reason, I can't call Pennington quite as dominant as the other 5, because his style makes it harder for our running game to do as well as it should.
