d line help

i sold everyone i had yesterday to revamp my team and im not sure who to get at le, re, and dt as my new guys. i still have sots nic scourton and donovan ezeiruaku who were my backups and not sure if i should run them as my starters and save coins until rush and have some other cheap cards back them up or pick up some other cards. they can be olbs or des for le and re it doesnt matter to me. my top picks atm for de are kyle kennard and von miller as they have the highest acceleration of all olbs and des and ill get my coins back from von whenever i decide to replace him since hes ltd. dt i have no idea none of them seem like game changers the majority of them either have no traits or traits but low toughness so thinking to just buy a cheap guy. i do have alfred collins bnd and still have walter nolen who i was contemplating on selling for the 89k since thats pretty high for a 94 overall dt
