The determination used for Spotrac and OTC are not clear to me. It does seem to heavily be weighted on playing time/starting but as we know that isn't always a determination of market value.
BC I don't know if he will return to us. It depends on his recovery. That was a really bad injury to have for a guy that will be very close to the end of his career. I hope he recovers completely and we get 2-3 more years of excellent backup play from him. He has been quietly one of our most valuable lineman in a long time, despite being a backup.
I am find keeping Corbett at the correct cost and as a backup. He has no business starting at Center anymore. Not to mention he can literally never stay healthy.
I agree on EDGE and QB. Two biggest issues by a wide margin(amongst the PILE of other issues). We have a couple of young guys that look to be capable role player replacements for Jones/Wonnum, but it is time to shoot for the moon and get actual upper tier pass rushers into Carolina again.
Final note, when I am pooh-poohing these reserves that you are falling in love with, it's nothing special I am doing. A bit of "eye test" with a healthy dose of realizing that most backups are backups for a reason. Especially when they have gone through multiple free agent cycles and the league has resoundingly said, "Nah." Not everyone is Freddie Luvu. Most are Christian Rozeboom's.
