Ok let's try to come up with a football team comprised of current NBA players. I'll start:
QB: For obvious reasons, a point guard would be a good fit for this position. I'm gonna go with Chauncey Billups, he has enough size and speed to handle the QB position. He's a great leader and makes big plays at critical moments. Jason Kidd would be my backup.
RB: This is a tough one to pick because there's not a lot of NBA players that fit the profile of a RB. I'll go with Baron Davis here. He's thick and built low to the ground. He's willing to take a lot of punishment (though he'd probably have to retire early because of it). Nate Robinson can be a 3rd down/change of pace back (he did play some football at Washington) .
WR: Kobe Bryant and Vince Carter. Both are insanely athletic and can jump out the building. I'm sure they can make the tough catches.
TE: LeBron James. He was an All-State WR in high school but he's a bigger body at 6'8", 240, so I'll put him here. Add another 10-20 pounds to his frame and he could be servicable enough as a blocker.
OL: Shaq would obviously be the left tackle in this unit with Yao being the right tackle. Andrew Bynum and Nene would play guard and Alonzo Mourning would be my center. There aren't too many 300-pound guys in the NBA so I have to settle for a few 260-290 pound guys.
DL: Once again, it's tough to find enough beef to fill out a football roster with. Eddy Curry and Carlos Boozer will play DT. Amare Stoudemire and Dwight Howard will play DE.
LB: Ben Wallace would be my MLB. I'm sure he can hit as hard as anyone plus he knows how to direct a defense. My OLB's will be Shawn Marion and Ruben Patterson.
CB: A.I. and Gary Payton. A.I. is your typical undersized CB but he can use his quickness and leaping ability to intercept balls from WR's. Payton may a bit slower now but he'll definitely harass the WR's.
S: Well, I think Bruce Bowen and Raja Bell would be natural fits at safety. Bell would be a free safety and Bowen would play strong safety.
ST (special teams): Steve Nash is the only player to my knowledge with a soccer background so he would be both kicker and punter. Leandro Barbosa would be my main return guy for kickoffs and punts with Monta Ellis helping out. I just pray that neither of them get hit. Kidd would be the holder and Tim Duncan would be the long snapper just for ****s and giggles.
