No offense, but college baseball fans are literally useless as a "source" on the signability of high school prospects. For one, very few of them know anything about the MLB draft in general, and secondly, they are highly biased towards whatever school they support. So no s***, Florida Gator fans think that he's going to make it to campus. The reality? If he's a first round pick, there is a 95%+ chance that he's signing. And if there was actually talk about him not signing, why has it not been reported by any draft writer who would certainly know more about the situation than Joe Schmoe the Gators fan? We already know that Al Leiter's kid has a $4+ million dollar tag that makes him a difficult sign...I haven't heard anything about obscene demands from Allen, which means that he should be signable.
None of this matters as he is highly unlikely to be in play for us at #11 anyway.
