Great athletes tend to shine in every sport at a high school level and even at a college level. Perhaps the jump can be made, but late teens and early 20s are crucial for mind/body coordination. Tebow is beyond that. I wish him well, but I doubt he’ll transition.
If he truly is seeking team...if that’s what he misses...then he should go with the Army or Marines as an slightly older lieutenant.
Actually almost none make it to the majors at 20, unless you are a Pujols, etc, trust me, there ain’t many of those. The odds are huge on anyone making it. I was just glad to get two years of school partially paid for!
