I think what JH and my post attempt to say is this has a massive red flag, and this is not directed at the OP, but rather the source of the information. Unless this adviser/agent is a personal friend, it would be pretty darn rare for them to make a cold call contact with someone to say 25th to 27th round. I think it would also be even more rare for an adviser,at this stage, to have access to national(reliable) scouting information to even know who would be in the top 1,000 potential draftable players.
My hope isn't to burst any balloon, but the information does not seem reliable.
