Kyle Fuller, CB
Fuller was drafted in the first round by the Bears in 2014. He had some great years in Chicago. The secondary is a position of need for the Bears this off-season. However, Fuller should not be the one to fill this need. He has not been playing well lately. Even though he played 16 games, he only started 10 of them because he was actually benched due to his lack of production on the field. In fact, he had a very mediocre PFF grade of 47.2 last year. Remember, this is on a scale of 0 to 100. Fuller is simply not the same player he used to be and he should be coming back to Chicago.
Nate Solder, OT
Offensive Tackle is another position that the Bears might be looking to upgrade. Rill listed Solder as a player they should not grab. I agree 100%. Solder is gonna be 34 next season and he is not playing great. He had some great years in New England earlier in his career but, ever since he joined the Giants, he has simply been bad. The Bears need to get younger and add some better talent via the draft for the offensive line.
Antonio Brown, WR
Finally, I think this one was obvious. I have made the case that some receivers that have a bigger character like Odell Beckham Jr. or JuJu Smith-Schuster could make some sense in Chicago. However, Antonio Brown is a no. He is very talented and it looks like he has some juice left in the tank. But, he is clearly a cancer for the teams he is on. Whether or not you think he was the problem or Bruce Arians, AB is not good for his team. He would bring so many distractions in Chicago. Brown is the last thing the Bears need in free agency.
