hes had 4 operations i believe, quotes from the doc. say hes good to go and he doesn't see him as being at any more risk than any other player, but it's always a concern. It's a risk, but if it pans out, it's great value. Crowder can play and he won't be thrown into the fire next year so he will have a year to test/strengthen the knees and see how they hold up and we will be able to evaluate if he can help us or not.
we need a successor to zt, he was the only viable option on the board IMO, good pick, hope it works out.
