‘The last spot comes down to Robert Foster, Isaiah McKenzie and Duke Williams. Versatility will likely come into play which all but eliminates Williams. McKenzie has been the Bills’ gadget player the last few years, but Robert Foster has the athleticism to take over that role and may bring more to the roster from a receiving standpoint. Foster will have to display some of the play-making ability from the second half of the 2018 season, however, if he hopes to claim the final spot.’
