This has nothing to do with Mac. Mac came into the league NFL ready. He didn't fall apart until his second year. If I am looking at comps in the league to Maye, I might look at Sam Darnold and Geno Smith who both failed because they were rushed into the starting roles too quickly and are finally proving themselves in their third or fourth team.
When Maye was drafted, most experts agreed that Maye's raw talent is off the charts, but his mechanics sucked and he came from a bad system that wasn't NFL style of an offense. He had a lot to learn. That is why I think he should sit. I always thought from the minute he was drafted that he needed to sit for upwards to the entire year until he is ready. He a lot to learn. More than any of the top QB taken this year.
If you wanted a QB who could start right away, you should have rooted for the Pats taking JJ McCarthy. If the Pats drafted McCarthy, I would probably be ok with him starting now. He came into the league more NFL ready.
