To Walt Aikens credit, his exceptional special teams play seems to be causing the Dolphins to try very hard to find him a spot on this roster. Special teams tends to always need more LB's, DB's, TE's and RB's. Those guys just seem to be within the parameters of what you need a lot of for special teams. Typically, the special teams coach is always trying to get more of those guys.
Looking at those positions on our team, it's kind of slim pickings at the moment. Off the top, I doubt these guys are being considered for core special teams roles: Reshad Jones, Byron Maxwell, Xavien Howard, Kiko Alonso, Lawrence Timmons, Koa Misi, Julius Thomas, Jay Ajayi. Some because they're needed more elsewhere, and others because of injury risks or age. Then looking at our special teams last year, the top performers were Walt Aikens, Mike Hull and Michael Thomas. I'm pretty confident that Rizzi is pushing hard for those guys. Hull looks like he is going to stick. Thomas is being crowded by the influx of DB's (IAQ out, but replaced by Nate Allen and TJ McDonald at S, plus drafted rookie Cordrea Tankersley at CB), but still looks to have a spot at Dime/backup Nickel with some versatility to be an emergency S. That leaves Walt Aikens in a tough spot for a roster spot.
Considering he faces the same squeeze that Michael Thomas faces, I think what they've done is shift Thomas out of the S rotation and into his more natural nickel/dime role. If Aikens couldn't get playing time last year, when our entire safety corps was out, then I doubt he'll have a roster spot this year at safety. So, his chance to make the roster depends on him bumping guys like Lafayette Pitts and showing that in an emergency, he can be serviceable at CB. I hope he can, because he's not being kept for his DB abilities, those aren't good enough. But his contributions to special teams are going to get him a spot on someone's roster, I hope it's ours.
