Patriot owner Robert Kraft testified in the first Aaron Hernandez trial. Patriots coach Bill Belichick could testify in the second Aaron Hernandez trial.

Via the Associated Press, Hernandez’s lawyers have added Belichick to the list of possible witnesses. The head coach joins offensive coordinator Josh McDaniels as persons who may take the oath and answer questions.

The potential purpose of Belichick’s testimony isn’t known. Typically, lawyers pump up the list with an overly broad list of names in order to conceal the actual case strategy that would arise if the lawyers listed only the witnesses who actually will testify.

Putting it another way, it’s like listing 20 players as “questionable” so that the other team won’t know who’s actually injured.

Already convicted and serving life without parole for the June 2013 shooting death of Odin Lloyd, Hernandez now stands trial for the July 2012 murders of Daniel de Abreu and Safiro Furtado. Jury selection has begun, and opening statements are scheduled for March 1.
