You clearly have no idea about either of these guys. For starters Calvin Johnson is 6'4. He is also faster than Larry Fitzgerald and Dwayne Jarrett (TO is a good comparison). CJ's estimated 40 time is 4.45, and Dwayne Jarrett's is 4.60. Dwayne Jarrett doesn't have a better abilty to catch the higher pass because he doesn't have as big of a vertical (Jarrett's is 38" and Johnson's is 45"). He is a possesion receiver, therefore both of your comparisons suck. Randy ran a 4.25, and Plaxico ran a 4.37. He is a lot like Keyshawn Johnson. The only thing you got right on was that you can't go wrong, both of these guys are and will be good.
Calvin Johnson, Dwayne Jarrett
CJ- 6'5 230 more physical, can run better routes, good after touch. has a 45" vertical
My comparison of him a Larry FItzgerald or a T.O.
DJ- 6"5 205 not phsyical, better abiltiies to catch the higher pass, clutch, and is very fast
My comparision of him Randy Moss, Plaxico Buress
YOU CANT GO WRONG
