Couldn’t we ask “why has so and so been on the roster” about others too? Ingram has been here for three years and in that time, there’s definitely been times where he could have stepped up and made himself more indispensable, given the problems we’ve had there recently (Elam bust, Belford injuries, Hairston injury), and what did he do to seize his opportunity?
Depends on your thoughts on whether the “window” is still open, has closed, or is still cracked. If Slay was someone you signed to “go for it”, then yes, you do what you need to do … plenty of Ingram’s come along every year (I’m not saying Slay was the missing piece, mind you)
