Again...see my post above about posters recognizing the use of an "example".
Nobody is using Frank Gore as "the rule". He is an example. You should be able to see the difference.
There is no such thing as "injury prone". There are players who play the game harder and with more abandon, and who, as a result, may encounter more frequent injuries. This doesn't mean they step out of the shower and blow out a knee by slipping on a wet floor. There are also players who get injured and then do not heal properly, making re-injury a greater likelihood.
TEs get banged up. Look at Gronkowski (an EXAMPLE, not "the rule" or "the exception" or any other illogical comparative). The NFL scouts understand that some positions take greater abuse than other positions, and that there are merits to strength training and surrounding talented players with other talented players so that the opponent cannot double-team any one player.
If a draft candidate has a solid physical and combine workout, no NFL team is going to bypass drafting a talented player for multiple rounds just because the kid missed some playing time while he was still in his teens.
This kind of armchair draft analysis is exactly why most of the porsters on this board should never (and will never) be employed as NFL scouts.
