If the Dolphins do not invest in better coverage LBs and a true FS us Dolphins fans will once again be disappointed. As the defense will get shredded by TEs and RBs again in 2018. The only difference would be that with better QB play the Dolphins should score more points and have a shot to win a few more games. However if they continue to stick their heads in the sand and ignore the LB and FS positions they will not be a serious playoff contender. I know there is only so much they can do with the resources they have. However the lack of speed and overall talent at LB and the lack of a Safety with good range needs to be addressed.
On Defense WLB, SLB, FS, & DE are pressing needs. Allen and Anthony still have a lot to prove on the field while Alonso is a known liability that they are stuck with due to an awful contract handed out to him last year. The goal is to get dominant players as starters and quality players as backups who can also play special teams.
