I'll be interested to see the comments that come from Polian and co. on the WR situation this offseason. I know Polian has been very complementary of Garcon in the past, and Garcon took a big step forward late in the 2009 season after struggling with inconsistency (drops, penalties, etc.). While Garcon is very promising, I thought Gonzalez was a little more impressive over his first 2 years. My guess is that the Colts try to involve both, while still giving some work to Austin Collie. This makes it very difficult for Garcon to put up the kind of numbers you suggest, especially the TD's. I think Peyton Manning tends to favor the more reliable veteran receivers, and this is especially true in the red zone. Look for Wayne and Clark to hog the red zone targets for at least another year.
I am not a Colts fan nor do I watch them much, but am interested in your comment about Gonzo. Why was Gonzo more impressive? I am honestly asking because I value a "homer's" thoughts; just saw Garcon rip through my Jets and would be surprised in Gonzo could have that type of impact.
I'm not down on Garcon, just really impressed with Gonzalez. In fact, I think both of them will be just a notch or two below Reggie Wayne if the offseason provides the expected boosts in health (Gonzo) and consistency (Garcon).The way I see it, the main advantages Gonzalez has over Garcon are in reading option routes and zone coverage, quickness in breaks, route running precision, hands/catching, and overall consistency. I couldn't find a really good highlight video, but this one shows a few good examples:

The ankle-breaking move at around the 1:00 mark is my favorite.
Gonzalez's skill set plays especially well in the Colts' system because Manning is so good at utilizing receivers with good precision and timing who can get good separation. In his second year, Gonzalez earned Manning's trust enough to get back shoulder throws in the red zone and become a frequent third down target. This type of chemistry is rare in the Colts' complex system. In this decade, Gonzalez and Addai are the only Colts skill position players who I can recall playing so well early in their careers. Reggie Wayne lost snaps to forgettable players like Qadry Ismail, Jerome Pathon, and Terrence Wilkins; Dallas Clark looked lost much of the time – and those guys will probably get HOF consideration by the time they're done.
In the end, I wouldn't be surprised to see Garcon get more snaps, especially if Polian remains in his corner. Personally, I see Gonzalez as a better player in the Colts' system.
