A few special-teams notes from a story I just finished writing: Josh Brown has made 15 of his last 16 FG tries. Nate Burleson’s 90-yard punt return changed the momentum against St. Louis. His 13.3-yard average ranks third in the NFL among players with at least seven returns. Craig Terrill has blocked two field-goal tries. Ryan Plackemeier has pumped up his net average from 36 yards in the first eight games to nearly 42 yards over the last three. Four of the last five opponents averaged less than 6.5 yards per punt return. Three of the last four opponents failed to top 21 yards per kick return. And with Burleson taking over on kick returns Monday night – he had a 45-yarder and a 25.8-yard average – that aspect of the game could be improving too. Denver ranks 31st in covering kicks. That is something to watch Sunday night.
