The only place I think you might be wrong is at DT. I think Vaughn Martin who we signed from the Chargers in free agency will wind up winning the other backup job over Chas Alecxih.
You could well be right. I didn't know anything about Martin, so I went with the guy we had invested a season in; but of course I could easily be wrong about that.
A couple of other guys who I think could wind up being surprises at camp are Keelan Johnson and Cameron Marshall from Arizona State.
I like both of those guys too. Marshall, especially. But I keep hearing about how much the coaches believe in McCray. Of course, they might decide to carry the extra safety at the expense of some other position. I also think one of the 2 UFA WRs might make it to the roster instead of Binns. I am rooting for Jasper Collins, from Div 2 Mount Union. He set all the records there; would love to root for him like I rooted for Bess. I am pretty meh on Binns. Of course, a veteran FA signing at cut-downs could trump all that.
Kelcie McCray is a free safety. He likley wouldn't be competing with Johnson. Rather he'd likely be competing with Wilson and Clemons. The reason he didn't play last season was because he fractured his foot in training camp. But he was a priority undrafted free agent that the Dolphins were happy to get. I think the Dolphins are hoping he can push Chris Clemons for the starting free safety position this year, but to be honest he'll be lucky to beat out Jimmy Wilson for the backup job.
Keelan Johnson is a strong safety, but he has experience playing both safety positions. He had a solid senior season with 88 tackles, 5 interceptions, and 13 pass breakups. To be honest I think he's a better prospect than McCray and Wilson. He'll be competing for a backup job behind Jones. I think he'll make a great replacement for Jonathon Amaya.
But I'm with you. I'm thinking McCray has a good chance to make the roster and replace Jimmy Wilson. Wilson is a safety in a cornerback's body. He was constantly getting beaten by bigger more physical receivers/tightends.
