Well that answers a question for me. It's not a matter of trying to "reseal" the cup after it was tampered with. The guy has access to other cups, lids, seals, etc. So if he did this as stated above (not saying he did) but if it was the case, the seals the lab gets would be absolutely perfect. Because he sealed the contaiminated portion with a brand new cup/seal. At that point it's just a matter of the signature, a signature that won't be perfect as it's likely a carbon copy and it's a pro baseball player so it's really just a scribble. Again, he might not have, but this would be VERY easy for him if he was motivated to do so. He has the urine, he knows who it's from, he has extra seals and everything needed to make it look legit. Again, not saying he did, but the fact that he had it for 44 hours, him and his son knew who the sample belonged to...it's certainly not entirely impossible to think that something could have happened during that timeframe.
