Former Chicago Bears wide receiver Allen Robinson is joining reigning Super Bowl champions the Los Angeles Rams after agreeing to a three-year deal worth up to $46million.

The deal includes just over $30m in guaranteed money, according to NFL Network's Tom Pelissero.

Robinson, 28, has long been considered one of the NFL's most underappreciated receivers, finding ways to produce with very little help from mediocre quarterback play.

Robinson has only seen more than 70 pass attempts thrown his way by two quarterbacks in his career – Blake Bortles (372 attempts) and Mitch Trubisky (300 attempts).

Now he gets a chance to prove himself with Matthew Stafford under centre, where instead of being the primary focus of the defensive game plan, he will start opposite the league's most productive receiver and reigning Offensive Player of the Year, Cooper Kupp.
