A freshman who has the size to play DL in the 3-4... and for the DL for the most part size is most of the battle. All they do is occupy blockers and let the LB's do the rest.

It is funny that Rhoads wants to slim down the D-line if that is the case. Don't we want them to get in the backfield? I think you have the roles of a DL and OL confused. If all DL do is occupy blockers than why did Suh have so many sacks, tackles for losses, etc.

You seem to think all a DL has to do to occupy blockers is to weight a certain amount and show up on the field. This is not close to being correct.

yes, i honestly believe some coaches prefer the "3 star" 5'11 high schooler over the "2 star" 6'4" kid.

Those coaches would be on GC staff and Mac's staff. But not on Iowa or Neb

You guys are thinking of 4-3 defenses. Their job is to be in the backfield. Its harder to find 4-3 DL because they have to to be big, athletic, be able to get into the backfield, and to stop the run. In the 3-4 they take up space and stop the run. The OLB's are the main pass rushers. Yeah its nice if they can also get into the backfield, but thats not their main priorities. It would be great to have all-americans at every position, but that doesn't happen. And as for the ****** asking why Rhoads wants to slim down the DL, well einstien that would be because we run a 4-3 defense. If you don't know how the 3-4 works, don't open a thread saying we should switch to it.

Shoot me for wanting to learn. I didn't catch that you were saying just 3-4 d-linemen were supposed to occupy blockers. I should know by now that a misunderstanding is a crime here.

"The defensive line is made up of a nose tackle (NT) and two defensive ends (DEs). Linemen in 3-4 schemes tend to be larger than their 4-3 counterparts to take up more space and guard more territory along the defensive front. 3-4 defensive ends were usually defensive tackles when entering at first. They must be strong at the point of attack and are aligned in most cases head-up on an offensive tackle. First and foremost, they must control run gaps. Size and strength become more of a factor for linemen in 3-4 defenses than in 4-3 defenses because they move primarily within the confines of line play and seldom are in space using athletic ability"

Hopefully that helps some of you to realize the DL jobs between these two schemes are completely different. I could be wrong, but I would think its easier to find a huge guys to take up space than it is to find big, strong, fast, and athletic guys you need for a 4-3.

Don't forget that in a defense, especially in a 3-4, an outside pass rush is much less effective if there is no push up the middle. If you leave a good pocket for the QB to step forward into, he has time to make the play. If there is a push up the middle as well as an effective rush on the perimeter, the play is disrupted and the QB must eat or throw away the ball before the play has a chance to develop.

Also keep in mind that in a 3-4, you do not generally have the personnel to rush both OLB's on every play. Therefore, the DE's must still be able to provide an effective pass rush on the side that the OLB drops into coverage. Part of what makes a 3-4 effective is the offense does not know which LB's are coming even if they are only bringing 4 rushers, just like a 4-3 front. The blocking assignments become more complex and it is easier to overload one side of the line on the rush without tipping your hand before the snap.

This is exact opposite of the truth. Bama has MT. Cody holding down the middle of their defense, thats why they can run a 3-4. Most teams run a 4 man front because there are hundreds more kids who fit that mold, where the kind of quality 3-4 DT is very tough to find. Basically there are lots of "uncoachable" things a 3-4 DT, mainly size and god given talent.

Yeah, great example using Terrance Cody. Since hes one of the biggest NT's ever, his size is the new minimum even though hes about 30 pounds heavier than your average NFL NT. So your saying since Cody is gone, Bama is no longer running the 3-4 right? NT Might be the one position thats harder to find. But the rest of the positions are much easier to fill.
