1. If you are gonna promise him a start, might as well promise him playing time as well.
2. If you offered him a scholarship, he should have sent you a letter back telling you if you are ahead or behind. If you are ahead...you don't "have" to spend more money to get the recruit, but you should never let a SIM recruit hang around. If you are behind after that 7th CV and don't have any money to even send a playing time promise...then you are cooked.
