I try to balance roster "predictions" with discussions of camp competition. I may have more locks than others, but we all know that there is always competition for the bottom dozen roster spots, as well as changes due to new additions and because of injuries.
For myself, these predictions simply mean that this would be the roster if the season started today. Obviously, posters have their binkies and different approaches to the value of low level talent (6th rounders, 7th rounders and UDFA's). Posters are sure that their favorites will make the team. Well, there are so many that 2-3 do end up making the team. And yes, I have a favorite among them this year: Halapio. Thomas may make it as a developmental #10 DB. I just don't think he is good enough to beat out both Wilson and Chung for a special teams spot.
That being said, for me, we have 2 special-teams "only" players: Slater and Ebner. I don't see either being beaten out for those positions, although it certainly "could" happen. As has been the case for years, Belichick considers a couple of special teamers as starters and key players, while posters consider these special teamers as bottom of the roster players. I think that we would be better off analytically if we included these 2 special teams specialists with the specialists: K, P, LS.
