I think Boldin is the best example to Benji. But as long as Cam and Benji stay healthy, Benji will have better stats. Boldin was stuck in Arizona's QB/online mess for years and still put up good numbers.
Boldin lead the NFL in YAC as a rookie.
Statistically, Boldin had one if the greatest starts to a WR career in NFL history. If he had missed a couple games his first 5 years....I think it might be the best and his 5 year start is still up there regardless.
Boldin IMO has more 89 to his game than anything. He lacked the explosion/speed 89 had obviously. Both have always been very physically and great YAC guys early on
