Why don't pro teams, and more so elite clubs get their their smaller players in the gym (more) and make them bigger and stronger to cope with the modern game (which is obviously becoming more athletic and physical). For example, players like David Silva, Modric, Ramires, Josh Mceachran, Benayoun, and even Peter Crouch! - imagine what a beast target man the 6ft 7' giant could be if he was bulked up. In regards to the smaller players like Silva, is it because they're afraid of the players becoming less agile? Do you lose agiltiy by gaining muscle mass (I'm talking about overall, not JUST upper body). I mean, look at a physique like C.Ronaldo, lots of mass, yet still as agile as players 5 inches shorter than him. In my view more muscle (=more strength, stability, balance) will make a player even more agile.
