20M
Invalid here for 2 reasons.
1. Here unlike some other leagues bidding is slightly different. They are in the form of total years @ fixed salary per year (where as for example CDD you pick years and divide total salary after winning bid to get per a year amount)
Technically this could be valid as 1 year @ 20m but I'd always like years posted
2. Also I believe with the franchise Tag options you only have 16.3m in cap to spend
