First, it has been reported we have been reaching out to Hoyers camp and nothing was happening. Maybe Hoyer doesn't want back or wants way more than we were willing to pay, both in money and years.
McCown was played for the new OC in Oakland. I would assume he knows the system.
We haven't given up on Manziel just yet. Possibly McCown who is older than Hoyer is a little more willing to take his three year contract and actually mentor Manziel. Maybe McCown plays this year, maybe not, but like it or not, teams don't draft a QB in the first round and then pretty much give up on them in year two.
I agree with all of this as well. Tampa had a shit o-line last year so it's hard to completely judge him on that year. He played well for the Bears recently as well so there's that.
