That's a very tough deal for Spencer. I feel for him and I wish him the best in his recovery.
I'm not a huge Spencer fan but I always thought he was a quality player that many under-rated because he wasn't posting huge sack numbers. I'm definately glad we didn't sign him to a big money deal because while I believed he was a quality player he wasn't a big money deal player, IMO.
Thankfully this time it didn't happen and now if he's not able to play again, which I understand is a possibility, then it doesn't hurt the Cowboys cap long term.
