I know I'm a little late with this and someone else has probably asked/answered it a month ago, but what is preventing a team from saying to hell with the draft cap, ignore it completely, and just scoop up every high level player that drops below the 2nd round?
Take the Yankees for example: Every year they draft 28th-30th anyway, so what do they really lose in forfeiting the 1st and 2nd round picks if they make up for it by getting 5-6 1st round talents in other rounds throughout the draft? They can scoop up every player that other teams are afraid to draft because of the new cap and sign them to whatever they want. I bet this will especially affect two sport high school players that previously had to be bought out of their football commitments with 7 figure bonuses.
If other teams are worried that it will take too much too sign those types and don't want to waste a draft pick or deal with negotiations it would just seem smart for the Yanks, Red Sox who draft so low every year anyway
