We can TRY to put Waller on the practice squad. The dangers of that are he has to be cut, then signed to the practice squad. When he is cut, a team can swoop in and sign him to their active roster, that's a big risk because he obviously has the talent to develop into a good player. He can also be plucked from our practice squad at anytime, so either way its a risk. Waller may just end up being the odd man out.
Honestly, I was hoping Pitta would retire. Its gonna be sad to watch if he injures his hip again. Also, he has regained mobility in the hip where he can live a very good lifestyle, if he hurts it again, complications will be worse. Every time he touches the ball I'm gonna hold my breathe, because it could happen even without contact (like last time). Maybe he comes back and performs well, which would be a bonus, but it's a long shot.
