I thought I remembered reading that Ryker wasn't doing all that well or that he didn't look all that sharp. I'll have to go back and look for it. Maybe I'm misremembering.
POB could probably use a RS year unless circumstances get crazy injury wise.
No they have said he looks solid. Rock solid for the #2 job.
O'Brien is the future at this point in time. If Armstrong goes down they just might hand him the reigns and start that future this year IF they think he can handle it. With a solid backup in Ryker to mentor and help him. Happens a lot with young QBs. Going to be interesting to watch.
