What do you consider "doing something" about the problem?
In the last 5 years, Miami has spent 2 first-round, 1 second-round, and 2 third-round picks on the OL. Their biggest free-agent signing last year was a Pro Bowl tackle.
The two 3rd round picks have done nothing in this league, can't give them credit for swings and misses. Dallas Thomas sucks and Turner couldn't crack the lineup last year even when all the guards were crappy and getting hurt. Line was destroyed with injuries and Turner couldn't even get some snaps at all. After the 2013 season Miami needed 4 new starting o-linemen. Only Pouncey was staying. They added Albert and James...ok fine, GREAT MOVES! Kudos!! If Pouncey doesn't get hurt last spring/summer they don't sign Satelle....what were the guards gonna look like last year with no Satelle? Signing Colledge who was on his last legs and was only good for a month or so last year before falling apart, that was a disaster! But, ok fine. Rome wasn't built in a day. I mean they had a ton of money to use at the end of the 2014 free agency period and draft, but ok. Fine adding Albert and James was enough for that offseason, let's make it a 2 year process. I'm down with that.
Then in 2014 the o-line struggles again, and they did what this offseason? They are going into the season depending on Dallas Thomas finally being good? Sign a marginal back-up in Walton! Hope Turner becomes competent overnight? They ignored the o-line this offseason.
Now if Mathis falls into their lap for .50 on the dollar then great (I think the odds are slim and none of that happening) and ignore everything I just wrote. But aside from signing Mathis this o-line is still a HUGE question mark and a mess going into this year, especially with Albert now coming off major knee surgery. So yes they haven't done enough to improve the o-line and needed to do more!
