I also vote REAL on this one. In addition to the great points made above in the 'real' department, I'd like to add the combination of patch and jersey. Most fakes are 100% patch, and 0% jersey. Otherwise you have to cut up a whole jersey, which produces very few prime pieces of patch. You know, the prime pieces that patch fakers use? Why would you put this boring patch in there?
None of these companies are perfect. You get patches in cards that shouldn't have patches, and jerseys in cards that should have patches. I even have a Sabathia that is clearly labeled "Laundry Tag" but it has a patch in it. I don't even think it was an "error" in 2001, I think they just threw whatever piece they grabbed into whatever card they were working on.
