I'm not pulling any GTs, so I started a new TT project. I saved all of the NCATs from previous releases that had all team chems from certain conferences (Saffold, Floyd, Whitehead, Suh, Emm. Sanders). I've also been running a 25/25/25 TT for some time with Fins/Niners/Rams. I realized that I had a lot of 3/5 team chems, so I started identifying roster spots where I could throw in a Stocking Stuffer, NFL Draft Past, or Team Diamond card to hit the 5/5.
I've never really thought of the strength attribute as having a ton of value, but when you're able to get +17 on Whitehead, it really changes the card. In addition, doing a 3x hybrid theme team gives Whitehead +3 everything. This method seems most valuable on his card, but it also made Saffold a viable starter. If you go for mostly AFC teams in backup spots, you can likely get +15 strength on Sanders as well.
If you sold the Whitehead, you can use the 93-94 PuP and he ends up a blue 99 for 20k (I wish EA would go ahead and make a training bypass). With Suh getting a 99 card, it took the value out a bit, but he was blue 98 at his 94 doing this.
You can see how I put it together here https://www.mut.gg/lineup-builder/436802ef-75b8-443e-95ff-48e22c09492c/. If you're running a 50/50 Rams TT, this is a no-brainer because Suh, Saffold, and Floyd get x2 Rams, plus their best FS is Weddle.
tl;dr if you use the Stocking Stuffer or NFL Draft Past cards in backup spots with the team chem NCATs, you can get massive strength boosts.
