What have we lost in the off-season that we have not replaced, or compensated for?
We lose Landry, but end up getting a reliable receiver, and anther receiver with great speed. We lose Suh, but pick up another premium DE with more rotating of the DT then the past few years. Lost our starting Center, yet replaced with a healthier Center, and a premium Guard next to him.
We are also bringing back a young LB (McMillan) that though will take a few weeks to start paying dividends, when he does, the LB Squad will be better (especially with how Baker and Alonso have looked), we will have better TEs then last year, Gore will be special for us, especially on 3rd and short, and in the RedZone...Finally, and most important, Tannehill is back.
I would not be surprised if 3 of those 4 wins you predicted, Miami gets in the 1st quarter of the season.
