If you are going to disagree with other people, the least you could do is have your facts correct.
First off, Marvin Harrison was about 1 inch taller than Sanders. Torry Holt? The same 1 in. Antonio Brown? 5'10. Brandon Lloyd? a bit over 1 in taller. Those receivers are considered average height. Not tall by any stretch of the imagination. Oh. And Marqise Lee is a rookie this year. You mentioning him with those others when he's accomplished nothing in the league takes away from your credibility.
The Patriots had already signed Amendola the year before to a similar contract that Sanders got. This idea that they were somehow outbid on Sanders this year is just not true as the Pats had the money to sign Sanders if they had wanted. You act like Sanders was the first free agent WR signed this off-season. He wasn't. He wasn't even the most expensive WR signed this off-season.
Denver didn't choose Sanders over Decker. They chose Demarcus Ware and Aqib Talib over Decker. Because those are the players they went out and signed immediately. Sanders fell into their laps after he backed out of his verbal deal with the Chiefs..
Your claim that nobody wanted Lafell is total BS. Otherwise, Lafell wouldn't have been signed so early in free agency and certainly not to a 3yr/$9M contract. It it had been April, I might agree with you, but it was the 1st week of Free Agency.
Lafell was signed because he's a complementary receiver who is TALL, isn't afraid to go over the middle, and can be a Red Zone presence. He was also signed because Gronk was coming back from a major injury, Dobson was coming back from injury, and to push Dobson, Boyce, and Thompkins.
