Definitely worth it.
Fitzgerald is gonna stretch the field and Emmit will keep the linebackers honest. This will create numerous seams for Anquan Boldin to exploit, and the result will be a prolific offense.
The three-headed combo of Fitz taking the deep balls, Emmit providing a decent running game, and Boldin being a beast on the intermediate routes will be too much for average D's to stop. McCown will be the direct beneficiary.
Before Boldin got hurt, McCown was the year's biggest sleeper. Now that Boldin has returned and Fitzgerald is comfortable in that offense, you will see Dennis Green's team make a strong 2nd half push. Green is one of the top 5 coaches in the game today and he will prove it in the second half of the season.
