Vincent Taylor is a tough guy but not versatile or agile and definitely not New England style. To play for the Patriots in a role like that you had to be extra special like Wilfork. They resurrected Danny Shelton from the Browns because he has more raw ability than someone like Taylor. I'm sure Flores is comparing Taylor to interior guys they had with the Patriots and Taylor simply isn't maneuverable enough.
The New England defense always looks vulnerable at times during the season. But they always have athletic types who can play narrow through gaps and come at you in waves. Taylor doesn't fit that mode so I'm not shocked he is gone. Willis is more of a fit.
Dolphins need to connect on the early round picks. Many of these late picks are touted as great finds but they really don't do anything for you in relation to the top teams in the league. Right now the Dolphins are no longer in pretend mode with guys like that. Flores doesn't see Taylor as someone he can win with long term.
Regarding Gaskin, I didn't follow preseason but he's a dependable high character guy, just the type of player the Patriots have utilized over the years, in spot play and special teams. Walton has more raw ability than Gaskin. I got challenged on that on Finheaven many months ago but I don't see how it was debatable.
