It's about being able to see over the line. Rex Grossman had this problem, he was like 5'11. I think the only QB I've ever seen successful at Kyler's height is Doug Flutie.
I think the Realmuto trade also makes Pederson a likely trade candidate since the Dodgers aren't getting him hence won't be moving Verdugo. I don't think anything happens though with Joc until Harpchado is figured out. At least anything considering us and Joc.
They have a lot of overpaid old vets is probably what he meant. Belt, Cueto, Shark, Longoria, Melancon, etc. I would assume they have enough income to spend like drunken sailors if they want though.
