Marino had lots of drives stalled by dropped passes. He had to throw the ball away from jailbreak blitzes many times. The big difference was that each time he took the responsible players to task for it and made sure they knew it wasn't acceptable. We rarely see that from Tannehill.
Most of the culprits continue to be repeat offenders. None of our TE's block worth a darn. That's why Lynch was drafted barely a year after Sims was drafted to be our blocking TE and failed. Clay runs 2 routes max, has sloppy routes and average hands and is an atrocious blocker. If it weren't for his speed and snap he would never sniff an NFL roster.
Tannehill is in his 3rd year and I expect him to step up in many ways. The biggest in my mind is stepping up as a vocal, take charge leader. Hold those OL, RB's and TE's accountable for poor blocking. Let those WR's know in no uncertain terms that the routes must be run correctly and precisely and if it hits your hands it's your mistake if you don't catch it. No more of this 'everybody gets an A+ just for participating' B.S.
