Great post!!!, Like others have mentioned the 3 players who really need to step up are Philips, Parker and Tunsil. Tunsil is has not displayed the immense talent that He showed in college so far on the NFL level. It's imperative that he take the next step at left tackle. If Tunsil becomes the player he was in his college days the offense should take the next step because he virtually will guarantee Tannehills protection on The Blind Side. If he can do that, the offense should take off. Parker has been nothing but an enigma at wide receiver. For every good game he plays he has several where he doesn't play as well or disappears completely and on top of all of that, he's constantly injured or playing with some sort of nagging issue. If Parker is somehow able to solidify the wide receiver position by giving a solid contribution on every given Sunday, would go a long way in helping improve Ryan Tannehill and the offense overall. But in my opinion it's Jordan Phillips who has the biggest need for a huge amount of improvement in terms of stability and consistency at DT!!! Like others I also believe that Spence will help along the defensive line but it still remains Jordan Phillips who can help the most on the entire team, if he takes the next step, the defensive line with all of a sudden become Rock Solid and steady something they haven't had in quite some time. I'm not a big fan of Jordan Phillips never was always felt that he was a player that was never going to reach his potential in spite of all of his efforts. If he should somehow turn on the lights and become solid I just hope Miami doesn't make the mistake of giving him a huge contract to stay with the team And reverts back to inconsistent player we all have come to know. Those are the three guys that I feel carry the biggest burden into the 2018 season.
