While many people like to point out the similarities between Tim and Collin (both home schooled, both know WWJD, both at the top of the list for greatest quarterbacks in college football history), I think it's worth pointing out a couple of key differences.
First, Collin is bigger. Tim left Florida at 6'3" 236 llbs. Collin 6'5" 230llbs, and with a year left, he'll be even bigger (superior weight room work ethic).
Second, Collin is faster. Tim was timed just under 4.7 in the 40. Collin runs it in 4.6.
Third, Collin plays a much more difficult schedule. The SEC East is basically the Big 12 North. Our current "round robin" schedule truly display's Collin's superior talent.
Fourth, Collin is smarter. Tim scored a 22 on the wonderlick, and the average for NFL quarterbacks is 24, his major was in Family, Youth and Community Sciences, so you can throw his GPA out the window (worthless degree that grades based on attendance). Collin is all big 12 academic team, and his major is Finance.
Pretty cut and dry...Collin is better than Tim Tebow in every way possible.
