This pretty much killed your flimsy argument -Too bad repeating the same spiel over & over isn't going to help you counter any of the facts I've presented.
TRY HARDER!
Martin's only good for stretching the floor at this stage of his career (even considering how poor his shooting has been) - he's a liability in every single other area. Johnson is better in almost every regard:
37% shooting on 4.0 three-pt attempts this season (Martin is shooting 37% on 2.6 three-pt attempts)
Can still create his own shot in any situation - one of the best late in-games (Martin is nearly completely incapable of doing so)
Can be a secondary playmaker, create for others - averaging 4 assists this season (Martin is nearly completely incapable of doing so)
Can work on the low block (Martin is completely incapable of doing so)
Can still play competent defense (Martin is completely incapable of doing so - he's a sieve)
Can play multiple positions in type different types of lineups (Martin can only play in one sort of lineup)
If you can't provide a counter argument other than mentioning career shooting/scoring numbers or 3-pt shooting (the only thing K-Mart is useful for yet Johnson is shooting better than him from behind the arc this season) - don't bother replying.
