In the case of Jason Pierre-Paul, who is still in the hospital, the Giants pulled their $60-million long-term contract offer. No information has been released about his injury and he refuses to see anyone from the team so beyond the initial announcement stating he had injuries to both arms and possible nerve damage nobody knows if he will be able to play this upcoming season which would mean he will play under the "Franchise" tag.
CJ Wilson may have just sunk his career with his accident, where he lost two fingers. He played in two games last year and has an unguaranteed $585,000 salary that runs through this upcoming season. If he does not play, he doesn’t get paid and he does not prove he is worthy of a future contract.
JPP had a solid year last year so his cards are holding their value for now. If he needs to take off a season or gets cut his prices will dip but if the damage turns out to be limited he can continue and his cards will rebound. Wilson has no cards, that I can find any way, so as far as his collectability goes it can not get any worse.
Hopefully both men will come out of the situation as best as possible under the circumstances and stand as a cautionary tale for people in the future.
