Q: I haven't seen anything about Philip Blake during the OTAs. (Manny) Ramirez and (Louis) Vasquez were said to be taking the first-team snaps. What gives? A: Judith, the Broncos selected Blake with the 108th pick of the 2012 draft, their second fourth-round pick of that draft. He was poised to push for some playing time as training camp unfolded last summer. Broncos executive vice president of football operations John Elway routinely commented about Blake's progress as the Broncos went through training camp. But Blake suffered a thumb injury in practice early in the regular season. The Broncos then put him on injured reserve Sept. 21. And while Blake could still talk to coaches, ask questions and work through any issues he had in the playbook, he could not practice. So, he entered this year's offseason program essentially still a rookie, much like a redshirt freshman in a collegiate program. Thus, he will simply have to regain the momentum he once had. And the quickest opportunity for him to play at the moment would come at center. Blake can play center or guard. J.D. Walton, who has been the starter at center since his rookie year in 2010, is still recovering from last season's surgery to repair a fractured ankle. Walton is doing some work with the team's strength and conditioning staff these days, but he has not returned to the team's full on-field workouts. He is not expected to participate until training camp. Experience counts in the league, especially for a team with title aspirations like the Broncos have. It's like a boxing match when you can't simply outpoint the champ.
