Most sports? Hardly. Sure you can, in theory, watch American Football, Rest of the World Football, basketball, and baseball on ESPN3, but if you want to see these sports played by teams that matter then you need regular ESPN or a cable subscription to view them. All the games that matter were removed from the ESPN3 lineup at least a couple of years ago.
It shows pretty much all college sports (at least, all of what's broadcasted on cable anyways -- and then some). Sometimes there's a blackout on a game, which is annoying, though....
It's just not that great for professional leagues.
I'm unable to access ESPN's live feeds without a login provided by my cable company. That login flags what ESPN channels I pay for so, for example, I can't watch ESPN U without paying for an upgraded "sports" package filled with garbage channels.
I do have access to some live and recorded events, but the selection is limited to filler content like college volleyball and minor league soccer. Another plus is the ability to use my neighbor's login without restrictions since our cable provider's flagging system is piss poor. As long as I know somebody paying for cable I can cheat the system.
This is not true. Unless something has changed recently, college football on ESPNU is not shown on ESPN3. This has caused more than one game I cared about to be (legally) unviewable for me.
