It would be easier for most people to score a bucket vs NBA players than to get a hit vs MLB pitchers or catch a pass/run 5 yards in the NFL. Not "easy", because most people couldn't do it period, just easier. For myself personally?
My basketball skills are trash. No shot, no speed, no handles, nothing. Now I'm more built for football and played so I think with a month if conditioning I could get a 5-yard gain---->i couldn't catch a pass though because I'm not fast enough to separate and I don't have great hands. Would take me a year of conditioning to be able to prepare for an NFL pass/route running...
But I understand blocking schemes, I have a strong upper body, lower body, and strong hands, and I can eat a hit. I don't think it would be easy certainly not in my out of shape place I'm in right now, but you give me 30 days, max 90 days of NFL-level conditioning, I'm getting that 5 yard gain...
I never played baseball so I'd never be able to do anything on a diamond. And I never made a basketball team, I understand the sport and I lack height, speed, and skills, but I feel like you give me 30 days of NBA-level conditioning and I'm getting that bucket...
