Your list illustrates just how many upgrades are needed on our D, 93.
My order of priority is slightly different, but we agree that there are at least 5 pressing upgrade needs.
Westbrooks
Quinn
Webster (because of Achilles)
TruJo (because of contract cap cost)
Barwin (If possible. Don’t know if enough draft pick or FA dollars will be available for this upgrade)
Barron (mostly a contract cut thing. Move Tree to Barron’s position and acquire another IL
Webster and TruJo are technically not upgrades, but rather forced changes due to injury and contract expiration.
And these are merely suggested changes on D.
We have several pending on O, too. Including Watkins and Sully decisions. Higbee doesn’t make my list simply because of the sheer number of other more pressing needs.
