I am greedy for more time with PFM at the helm of the Broncos. He is an amazing player and I think could play several more years if he wants. His style of play and quick release cuts down on the punishment he has to absorb each year. I think Warren Moon played until he was 43. Farve was 41 I think when he retired. Another 3-5 years for PFM would be fine by me.
I think it is unlikely he will retire because of injury or age making him unable to compete at a high level. Its just a matter of what he wants to do. Hopefully he will stay hungry for more records and more rings. (Can't have little Brother with more SB rings than him)
