Pujols has a chance to surpass Gehrig as the greatest 1st baseman ever. They are remarkably similar players. Check out their 162 game avgs against each other: Gehrig: .340/.447/.632, 179 OPS+, 37 HR, 40 doubles, 12 triples, 149 RBI, 141 Runs Pujols: .334/.425/.622, 169 OPS+, 42 HR, 44 doubles, 2 triples, 127 RBI, 124 Runs Now, of course, Gehrig put those average figures up in over 8000 AB's, Pujols is around 4500. He has a long way to go, but it is possible he'll pass Gehrig and Foxx. He must have many more seasons of dominant numbers though to achieve that.
