1 and 3 are my worries. And I hope even if he is a 5yr and can't go he still doesn't have any issues with the foot. As far as 2...if he is top 10-15 of CBs. I wouldn’t love it but it could be much worse.My concern point 2: how good will Sting be.
My concern point 1: how long and what level of good will he be.
My concern point 3: how soon does he re-injure?
