Why is it all QBs give me - chem?

I currently have P.Rivers as my QB who gives me 0 chem but how come everyone eles gives me like -10? i really want micheal vick and i have 2 eagles WRs so he shouldn't have that low chem? should he? i am new to Madden so sorry if this is a novice question.|||i have similar problems. New to Madden but have played fifa ultimate team but this is a lot different. Is it just same team and/or college that gives chemistry? Not same division?
Which players link to provide the chemistry? does the RG and LG link for example or is it just the LT and C for the LG? So far i have just stuck with the original players whilst i figure it out.
Planning a team is going to be difficult given i dont know half the names let alone what college they went too.|||It is very easy to get your chem to 100 following these steps.
Find players that are either on the same team, played on another team with those players or played in the same college. Flip the card over to see what college they went to.
You want a different player in every starting position on your roster...every position must have a different starter. You can use duplicates for easy chem but people frown on that. I find its okay to use duplicates as long as they are just backups and not 4 Rice's on the field at the same time. Having the a duplicate of the same WR/CB/RB in your KR/PR and 3DB slots aren't bad. Use 2 different kickers one for KOS and one for reg K. Don't use the same card in more than one slot unless it is a duplicate.
Jerseys, Playbooks, Coaches and Stadiums also change chem as well.

need to find an idiots guide for this so i can work out what the hell im doing. I can tell the contracts are going to kill me as they seem expensive as well.|||stock up on contracts from the bronze packs...you usually get a contract and an injury card in every pack and if you delete all the cards you don't need you usually recover 200 coins back and sometimes you can even make over 1000 coins from just deleting a bronze pack. some cards can even be auctioned for a profit such as coaches and stadiums on occasion.
