QB - Joe Montana: The man was the definition of "cool under pressure". And he has 4 rings.
RB - Barry Sanders: I really don't think this one needs a reason why, but I'll give one anyway. He broke a man's ankle without touching him, he was easily on his way to breaking numerous records when he retired (which is the only reason why Crybaby Emmitt stayed in the League so long), & he did all of it without a good offense or a FB. A legendary career cut short by bad management.
TE - Mark Bavaro: Big physical end that could run you over & make big plays. I always remember him being super clutch for the Giants when they seemed to need him the most.
WR - Art Monk: Despite the lack of a "signature catch" (

), he was the clutchest of clutch receivers IMO. When you needed a 3rd & 16, he was there. He had the best hands in the game. You could throw the ball anywhere within 5 yards of his position & he would catch the ball & make something happen. He was also the classiest guy on the field.
WR - Jerry Rice: Next to Monk, Rice was my other all time favorite receiver. Also a class act & non-stop hard worker, his record breaking career is by & large one of the most celebrated of all time at his position (or should be). No matter where he went (even in Oakland...or was it LA at that point...I can't keep up with those clowns), his work ethic & his abilities never ceased to amaze.
That's my team.
