Defensive Tackles/What is Rex Seeing? (Does weight matter a ton?)

[BishopMVP]

I'm running a 4-3 Under, Rex'ing Depth Charts/GamePlan, and it seems I have to jury rig everything to get Bertolini (who should be an above-average starting DT) the majority of PT. It'll stick 3-tech DT's in over him, it'll move my 3rd good DE into that spot, but these two guys side by side show the starkest contrast.

Stuart is 5'11, 308 - is he starting over Bertolini simply due to weight? Does Rex value PRT/PRS more than Run Defense/Play Diagnosis for PT, but not for overall rating? It does seem like the computer really values run defense when determining DT's overall rating - look at my other backup.

(Fwiw play totals are 45 for my 4th DT who's only a 46 overall, 44 for Stuart, 30 for Bertolini, 29 for Walsh.)

Does Walsh have a chance to be a really good player, or is he going to be a complete bum with so many 0's? Is Bertolini worth monkeying with game plans to make sure he gets the majority of PT, or is he an overpaid bum I should cut or trade at the earliest opportunity?

Heck, as long as we're on the subject, here's an even more egregious example at MLB. Catron is 6'2 252, which is literally the only thing he has going for him except Endurance. I suppose this could simply be a case of Catron playing in whatever formation we started in, because Embry outsnapped him 38-35, but that would still seem to be an argument in favor of global PT settings, as Embry should be in 100% of the time I need an MLB until he's tired.

I think the weight debate (and height for that matter) is the no.1 question that I would like to see answered. Just how much does it count for...and is the right weight more important in certain position (hope so). We have to presume the search lists accurately reflect weights influence. But some stat testing to confirm this would make me feel a lot better.

Caracatus did some great work for FOFC in the past, in relation to combine to bar correlation. When he stat tested QB height with performance in FOF7 he found nothing. 6-4 may well of been 5-9. With so many variables in the equation it got lost, presumably. Or maybe it was never intended to be a big deal. Perhaps that explains why I am a little reserved about the effect of player weight. There always seemed to be a lot of bars in FOF that basically did sod all, window dressing if you like. Certain bars dominated proceedings. It was addressed at times to be fair (sense rush, BPR) although certain bars just sat there and were ignored by veteran GMs.

Caracatus plans to have a look at weight and height (again) in the new year.

I can see the results of this work making or breaking FOF8 for me. If anyone else out there with the skills could dig into this sooner, I think that would be great.

From the help file:

One primary difference between 34 and 43 is that since defensive linemen usually rush the passer, and four defensive players are usually involved in the pass rush on a play, the 43 is more predictable in terms of where the rush is coming from.

Left Defensive Tackle (T): Lines up in the 1-technique to the strong side of the center, and is responsible for the A-gap on the strong side. Since there are four linemen and the 1-technique tackle is always headed into this gap, he should be a little smaller and more athletic than a true nose tackle.

Right Defensive Tackle (T): Lines up in the 3-technique to the outside of the left guard, and is responsible for the B-gap on the weak side. The 3-technique tackle in a 43 can be a little smaller and more athletic than most tackles and may actually generate considerable quarterback pressure.

They are definitely pass rushers through the gap, but really Bertolini is in the no-man's land between ideal weights for DT and DE in a 4-3 Under. I think this is a combination of weight and Pass Rush bars.

As for Catron, the MLB is primarily run support in a 4-3 Under. He does drop back into pass coverage, but his run bar is a big deal. Both those guys are heavy for a 4-3 Under, though, with Embry being much closer to the 238 ideal weight. Agreed that Embry should probably be starting there.

As far as Embry goes, endurance has a huge, huge role this year for me. Outside of the offensive line, guys with ridiculously low endurance do not get 75 or 80 percent of the snaps anymore.

I have two defensive ends in my 3/4 that are about the same weight, same level of talent. Both are on the depth chart the same way. One guy has an endurance of 91 and plays virtually every snap. The other guy has an endurance of 47. He usually end up with an 83% or so snap rate.

That's the best example I have now, because I've worked to rid my team of most low endurance guys because I can't keep them on the field.

Endurance is huge for me also, I've noticed in SP that I can be losing a game horribly going into late 3rd/early 4th (20+ points) and make a comeback solely because of it, reason for this is: looking at game logs my starters are still in (high endurance) and the AI had to pull his starters because of low endurance so I get about a quarter to a quarter and a half of my starters vs the AI's backups
