well, whoever picks him up is getting a pretty good deal I imagine, the fact that his value has gone down might help a team sign him under slot value I assume; but as I said before Im not the most well informed when it comes to the MLB draft.
just in watching I heard them say Stanek was falling due to "durability" issues but no specifying what exactly they meant by that, especially since not all that long ago he was considered top 10-15 talent.
