It is doubtful that Reggie will resign unless he's willing to take less than market value to stay. With all the money the Colts have tied up in Marv and Peyton they won't have the money to give him what he's worth and still field a competative team, if they thought they could give people what they desrerve and still compete, they would resign Edge long term instead of franchising him and letting him go next year possibly.
They also have two other wr's they like very much in Troy Walters and Aaron Moorehead. Out of those two, Moorehead is the better fit to take Reggie's place. Walters is more of a slot guy and return man.
They may plan to move Stokely to the #2 but I would say that would depend on whether or not he shows he can stay healthy this year.
Roscoe is typical Colts kinda move. See undervalued talent that they think they can sign and develope. If he shows the kinda talent that peole were raving about when he started his college career and continues to improve, he has a shot, but they...and me, really like Moorehead too. Decent size and has the ability to run good routes and go get a ball. They may plan to use him on kick off returns too. A coupla years ago they signed Brad Pyatt in the same kinda situation and he's avg like 25 yds on ko returns but has missed 16 games in 2 years. Maybe that's their plan with Rosco.
Obviously the Colts convinced him he has a chance to play somewhere in the next year or two as he had three other teams, including the Chiefs trying to sign him and Kansas City would have given him a better chance to play sooner. Shows he has intelligence, looking at the big picture and taking Manning and a crowded wr corp instead of the quick cnhance at PT in Aarow Head. Also knows he has a chance to learn from the preeminent wr combo in the league. You could do worse if you know you're a project.
On a side note, Roscoe was also drafted to play baseball a coupla years ago but chose football at Clemson.
