I would pick up Aqib Talib and Dez Bryant in the coming weeks if I was the Saints

So we would release 3 young cheap and at times effective players for the corpse of Dez Bryant and others?? So in a box maybe that sounds smart to you.
Speaking of smart, I said release one of them, not all 3 for Dez.

In 9 games, the combined numbers in those 9 games for Carr, Arnold, and TQS are: 15 targets, 9 catches, 122 yds . For comparison, Taysom's receiving numbers are 12 targets, 9 catches, 100 yards. So, yeah, no one's going to miss anyone of them. Well, you, I guess.

But unless an apocalypse occurs we might wanna be prepared for a 2020 season.
If the Saints are going to prepare for the 2020 season with these 3, then I guess they'll go unprepared into the 2020 season.

I’m not sure needing 4 wide receivers in the offseason is a great way to build a roster, unless we add Ocho cinco, TJ Houshawhateva, and Roddy White to the mix. SMH
The Saints need the WRs now, but putting that aside, It's not like you can't find similar production from players off the street. And it is not like teams are going to rush to sign any of them if released. They will be available next year if released.
