The Detroit Lions have made Calvin Johnson the highest-paid receiver in the NFL, signing the star known as Megatron to a new eight-year contract worth up to $132 million. The team announced the signing Wednesday, the second day of NFL free agency. The player\'s agent, Bus Cook, said the deal is worth $60 million guaranteed if Johnson plays all eight years through the 2019 season. It is one of the richest deals in the league and tops the one given to Arizona receiver Larry Fitzgerald last year, an eight-year deal that could pay him as much as $120 million, with $50 million guaranteed. Johnson, a five-year veteran, is a two-time Pro Bowler and his 45 touchdowns receiving are the most in the NFL since 2008.
