the past has nothing to do with a comeback, based on his current form from his recent EX
he isn't in top form and what are his motivations, to get more publicity for what ?
thats why I see Weir has better chance of a good comeback results
quadless Evan is also technically deficient
let's afce it, not everyone is like Pluschenko who is a God and can comeback anytime
anfd there is no need for Evan as Brown is by far the US superior skater if he can develop just in time for 2014 and also the lesser talent Farris although not as good as Brown technically or artistically can have better impact that Evan's comeback

people say Evan can't make a convincing comeback because he doesn't have a quad, and Jason doesn't even have a 3a yet! Anyways, about this whole "lesser talent" that is Farris, have you seen his 3a? Evan and Jason WISH they had a 3a like Josh Farris... Further, the last time Evan attempted a quad in competition (2010 Nats) it was a hot mess, compared to Farris' 4t attempt at 2012 Nationals which was a really good attempt very close to full rotation.
Jason is not the answer until he starts attempting and landing 3a and some sort of quad in his competitive programs. Simple as that. Whether you care for his artistry or not, Josh Farris has better chances than Evan or Jason because at least he is attempting 3a and 4t in competition, period.
Evan can be competitive if he comes back, retains his 2010 form, starts attempting (at minimum) one quad in the FS and can at least rotate it consistently, and hopes his skary 3a technique doesn't make that jump inconsistent and that his PCS are as monstrous as they were in the 09-10 season. That's quite a tall order, so I tend to think he won't come back.
Johnny's odds are better because it appears he has a quad and his 3a is stronger than Evan's.
Jason Brown is going nowhere until he gets a 3a, and probably until he gets a 3a and a quad.
Josh Farris can feasibly pass Rippon, Miner, Dornbush, and all others save Abbott and maybe a convincing Johnny or Evan comeback as early as next season so long as he delivers in competitions and is consistently trying the 4t in his FS (which is the plan), he has the goods to do so and we saw how high his PCS got at JW, they are comparable to Rippon/Miner international PCS and higher than Dornbush international PCS. Unless Jason gets a 3a and quad in the course of the offseason, he won't be able to do this.
