Questions on Boosts

Hopefully I am posting this in the correct section. If not, please let me know and I will move it. Many cards (Coaches and Leg Players specifically) have boosts associated with them. However, there really is no way to know which boosts are in play at any given time that I know of. I assume that a player or coach just has to be in one of the "starting" positions that impact chemistry for their boost to count. Here are my specific questions/thoughts:
1. Does a player have to be in a starting position for the boost to work or just on the team? Does he have to be in his primary position if he has to be starting? For example Deion Sanders gives a man coverage boost. If I play him at CB3 (a non-starting position), but he starts a KR, does his boost count or does he have to be starting at his natural position of CB?
2. If I have multiple cards with the same boost, are they stackable? For example if I have Barry Sanders with +7 Run Block and a Coach with +3 Run Block, do I have +10 Run Block or is it just the higher of the two?
3. How do I know what boosts I am getting at any given time? Are the players stats altered in the depth chart to accommodate the boosts I have in play? It would be very helpful to have a "boost dashboard" in the lineup section where you could see all of the stats in the game and which ones you currently had a boost impacting...also by how much. This would be similar to the chemistry bar, but for every stat.
Additionally, I have a suggestion for the Depth Chart section. In MUT 11, the depth chart screen used to show you the image of the card you were highlighting on the right hand side. This made it very easy to see the stats without scrolling and to determine which version of the player you were putting in. The new MUT 12 screen just shows the depth chart itself without the cards. Is this going to be reactivated for MUT 12? It would be a tremendous addition.
Thanks for your time.|||Great post! I was wondering a lot of the same things! Hopefully MUT support will resond on this one.
AGREE BIG TIME with the last part as well about having the card image in the depth chart like in MUT 11! That was very helpful and I wish they would bring it back!
