A weekly look at what the New England Patriots must fix:
With the Detroit Lions coming to town on Sunday, the Patriots have some cleaning up to do on special teams, an area where they're usually solid.
The Patriots had three penalties on special teams in their 42-20 win over the Colts -- illegal blocks by safety Tavon Wilson and cornerback Malcolm Butler, as well as holding call on safety Patrick Chung.
Also, wide receiver Danny Amendola fielded one punt at his own 5-yard line, a debatable decision as Butler also couldn't hold his block against gunner Dewey McDonald and Amendola was dropped for a loss of 1 yard. Kickoff coverage was shaky as well, with Kyle Arrington potentially saving a big return in the third quarter when the Patriots' spacing was off, and punter Ryan Allen booted a touchback in his only attempt.
The Lions, with Jeremy Ross as their primary punt and kickoff returner, rank in the top 10 in punt return (10.2) and kickoff return average (24.9).
A big part of what has the Patriots on a roll of late is playing complementary football -- offense, defense and special teams -- and it's the third phase that was a little suspect in the team's most recent victory.
