You're acting like I didn't like MG, I did. I was happy with his performance for the most part. I think as fans we get a little too attached to any sort of bright spots on the team. I think Gilli was a great compliment to McCoy, but there is no reason to think he could be the full-time starter after Shady which was basically the contract was signifying with the amount of money in place. Look at his stat line. Most of his damage came in relief of Shady with a limited amount of carries. Another stat to note is the number of times he carried the ball 15 times or more when shady(6 games) was out of the lineup? Twice. Season Finale against the jets in 2015 24 carries for 28 yards and the season finale in 2016 with 15 carries for 40 yards, not so great, his 5.7 YPC average started to dip once he carried the ball more. Even with his biggest Cheerleader/Fan, Rex didn't give him the opportunity to carry the load in Miami with McCoy obviously suffering from a hamstring injury.
The price was just too steep for his value to this team, cannot forget the money invested in the RB/FB position DiMarco, Tolbert, and Williams attached to McCoy's big salary.
