If the Browns get 'Vicius and another talented WR in FA for less than Bryant, then I say go for it. However, this is a mediocre year for WR's, with David Givens, Randle El, Reggie Wayne, and possibly Bryant probably commanding (and possibly getting) more than good market value. Aside from those 4, it gets pretty mediocre with the likes of 'Vicious, Corey Bradford, Reche Caldwell, and Jabar Gaffney heading the "second tier". Maybe they could target Santonio Holmes in the draft and bring him along slowly while Edwards, Northcutt, and Jurevicious run the show? Don't forget about Winslow V. 2.0, although will he be ready for next season?
I've always been impressed with Bryant's ability, but if he couldn't get his head screwed on right with Parcells, you have to wonder if he'll ever mature down the road.
