Now that the muzzles have been removed for NFL team executives and the players they either re-signed or added in free agency, Thursday was a time for explanations and reflections. Yes, there were more transactions: Las Vegas getting running back Kenyan Drake while Denver bid adieu to RB Phillip Lindsay. New England bringing back Kyle Van Noy, Buffalo grabbing Mitchell Trubisky, and Tennessee getting All-Pro long snapper Morgan Cox. There also were plenty of words from guys switching teams (Carson Wentz, Ryan Fitzpatrick, Joe Thuney, A.J. Green), players staying put (Leonard Williams, Derek Wolfe) and even a player coming out of retirement (Kyle Long).
