you can use the money slotted for the first round in other rounds IF you sign the first round pick under slot....and for the record i hate that he said that bc it implies he'll draft another reach pick that he can pay underslot to save money for later rounds - a strategy that imo failed last year
if you draft a player in the fist round and dont sign him you lose the money completely...you then have your original bonus pool minus the money allotted for that pick (for 11th it should be roughly 2.6 mil i would say) and the same restrictions/penalties apply to your new cap
if fact, its worse bc the percentages represent much smaller sums....so lets say you sign your first round for exactly slot value...it means you can actually pay your other picks more bc you would still be exceeding your bonus pool by a lower percentage than if you made the exact same signings w/o the money from the first round pick...im hoping this is what alderson meant and not that he would draft signable guys that will take underslot value
