‘Considering how bad the Buffalo Bills’ kickoff coverage looked on its final play of the 1999 campaign, maybe fans should be a little more forgiving when watching this year’s unit get the kinks out. The Bills, who covered dozens of kicks in actual games and countless more in camps and practices, were embarrassed when their season ended on the Tennessee Titans’ now-infamous Home Run Throwback return. So if the Bills’ special teams can have that sort of letdown after all that repetition and with their playoff lives at stake, it only stands to reason those units will experience some growing pains this year with a new coach and a slew of young players. "They’re going to make mistakes," coach Wade Phillips said after Tuesday afternoon’s practice at St. John Fisher College. "I saw the aggressiveness I want, but some of the techniques and mental mistakes we’ve gotta correct. We’ve gotta get that aggressiveness tuned in."’
