The Bills opened training camp Sunday morning with WR Isaiah McKenzie running in the slot with the 1st team, according to Aaron Quinn of the Cover 1 Buffalo podcast. Veteran free-agent addition Jamison Crowder, meanwhile, was splitting 2nd-team reps with rookie Khalil Shakir. It could just be the Bills leaning toward the incumbent to open camp, but the Buffalo News also called McKenzie the "slight favorite" to win the starting slot gig earlier in the week. The Bills added Crowder on just a 1-year, $2 million contract -- far from starter money for a WR. We'll keep watching this competition through the summer. It looks like we should at least consider McKenzie the leader for now, though.
